Who Is Jesus?
A Comprehensive Study of Christ's Identity, Origins, and Work
Introduction
“By what authority are you doing these things, or who gave you this authority to do them?”.
Mk 11:28
When Jesus appeared in the flesh on the stage of humanity, there was never a moment's doubt that his power exceeded human capabilities. The balance of power was quickly established. The people who had waited so long for the promised Messiah King had long since lost their personal relationship with God. Their principles did not allow them to step outside the confines of their expectations and religion. Direct confrontation with the supernatural did not help: they remained hostile.
For us, however, this conflict is a great help: we have nothing to lose, we are free to ask: is the power that Jesus has from Heaven, or should we wait for someone else to save humanity?
Below, we examine the person of Jesus from three perspectives: his human origins, his heavenly prophetic origins, and his earthly work.
Mk 11:28
Chapter 1: Human Family Line - Christ Is the Offspring of Abraham
1. The Genealogy of Jesus
Matthew opens his Gospel with a deliberate and purposeful genealogy that establishes Jesus' rightful claim to be the promised Messiah. The genealogy demonstrates two critical truths: Jesus' legal right to David's throne through Joseph, and his fulfillment of God's covenant promises to Abraham. Matthew records Jesus' lineage through Joseph, tracing the legal succession to the throne of David. This genealogy is structured intentionally into three groups of fourteen generations each - from Abraham to David, from David to the Babylonian exile, and from the exile to Christ. This arrangement is not coincidental; the numerical value of David's name in Hebrew equals fourteen, symbolically pointing to Jesus as the promised "Son of David."2. The Society He Arrived To
The first-century Jewish world into which Jesus was born was a complex tapestry of religious fervor, political tension, and spiritual longing. Understanding this context illuminates both the challenge Jesus faced and the revolutionary nature of his ministry.Religious Leadership and Parties
In the first century, religious life in Israel was dominated by several competing groups, each with distinct beliefs and practices:The Pharisees were influential teachers and interpreters of the Law who had considerable sway over the common people. They developed elaborate traditions and interpretations that extended far beyond the written Torah. By Jesus' time, many rabbis had created burdensome regulations - for example, defining precisely what constituted "work" on the Sabbath in such minute detail that ordinary people could barely navigate daily life without violating some rule. Ancient rabbis taught that on the Sabbath a man could not carry something in his right hand or left hand, across his chest or on his shoulder, but could carry something with the back of his hand, with his foot, elbow, or in his ear.
The Sadducees represented the priestly aristocracy and held power in the temple. Unlike the Pharisees, they rejected beliefs in resurrection, angels, and spirits, accepting only the written Torah. They were politically pragmatic, maintaining cooperative relationships with Roman authorities to preserve their positions and the temple's operation.
The Scribes functioned as professional interpreters and teachers of Scripture. As most of society was illiterate, scribes held tremendous authority as guardians of the Law. They established schools and served on the Sanhedrin, the Jewish ruling council.
The Zealots represented the revolutionary wing of Judaism, fiercely opposing Roman occupation and willing to use violence to achieve political independence. Their messianic expectations centered on a military deliverer who would overthrow Rome and restore Israel's sovereignty.
The Essenes, though not mentioned in the Gospels, formed separatist communities like the one at Qumran. They considered themselves the only true Israel, rejecting the temple priesthood as corrupt and awaiting divine intervention through messianic figures.
Political Reality
The Jewish people lived under Roman occupation, administered through puppet rulers like the Herodian dynasty and Roman governors such as Pontius Pilate. This foreign domination created constant tension. The high priesthood had become a political appointment rather than a purely religious office, with Rome ensuring cooperative leaders held power. Taxation was oppressive, collected both by Rome and for temple maintenance. Tax collectors were despised as collaborators with the occupying forces, often grouped with "sinners" and "prostitutes" as the dregs of society. Economic hardship forced many farmers from their land, creating a class of landless poor and even bands of outlaws who resisted the wealthy elite.Spiritual Condition
Into this world of religious complexity and political turmoil, Jesus arrived to find a people whose "hearts grew cold" and whose "intimate knowledge of God had faded." The religious leaders had transformed genuine faith into a system of external compliance. They emphasized ritual purity, Sabbath regulations, and proper tithes while neglecting justice, mercy, and faithful love for God. The Pharisees often publicly challenged Jesus' authority, testing him with questions about divorce, taxes, and his interpretation of the Law. They were more concerned with protecting their positions and traditions than recognizing the Messiah standing before them. The chief priests, scribes, and elders repeatedly demanded to know by what authority Jesus performed his works - revealing their spiritual blindness despite all their religious knowledge.3. His Empathy and Representation
Jesus, who is Christ, who has become Our Word in flesh, perfectly represents the Heavenly Desire already articulated in prophecies: Jesus fully identifies with the sins of the people in every way, desiring mercy - that is, according to Hosea 6:6, the knowledge of God, and not dedicated sacrifices, since the Father desires relationships, not principles. So the Son embodies this. He is the incarnate word of God. However, the Big Wall of Separation between God and man must also be demolished. Jesus arrives in a vacuum where:- Hearts grew cold
- The intimate knowledge of God has faded
- Destruction is approaching (as we will see in a few years in the history of Jerusalem) Jesus' arrival in this context demonstrates divine compassion. He didn't come to a spiritually thriving people who merely needed minor course corrections. He came to a people trapped in religious externalism, political oppression, and spiritual deadness - exactly the people who most desperately needed a Savior who understood their struggles and could bridge the chasm between holy God and sinful humanity.
Chapter 2: Jesus' Prophetic Message in the Old Testament
Christ Is the Offspring of Abraham and the Last Adam
The biblical narrative presents Jesus not merely as another figure in Israel's history, but as the culmination of God's redemptive plan extending back to humanity's very beginning. Paul's teaching in Romans 5 reveals a profound parallel between Adam and Christ that illuminates both the depth of humanity's problem and the glory of God's solution. Let's take a closer look at this!The First Adam and the Last Adam
Adam stands as the first representative head of humanity. Through his disobedience, sin entered the world, and through sin came death - not just physical death, but spiritual separation from God. Paul writes in Romans 5:12,- Adam's sin → humanity condemned in him → eternal death
- Christ's righteousness → new humanity justified in him → eternal life We will talk about our righteousness later on.
The Superiority of Christ's Work
While Adam is a type of Christ, Paul stresses that the comparison reveals Christ's superiority through several "much more" statements. The free gift is not like the trespass. If death reigned through Adam's sin,*they will reign in life, not death. Why "much more"? Because God's ultimate purpose is not judgment but the display of the glory of his grace. Judgment is real and necessary, but it serves as the backdrop against which God's abounding grace shines most brilliantly. The glory of God's grace is the glory of Christ applied to all who are in him.
Universal Significance
This Adam-Christ parallel demonstrates that Jesus is no tribal God or limited, local Savior. If Adam is the father of all human beings, and if the fundamental problem with all human beings is found in how we are related to Adam and what happened to us when Adam sinned, then everybody in the world - no matter when or where or who, whatever tribe or language or culture or ethnic identity - everybody has the same fundamental problem. Therefore, if Jesus Christ is the "last Adam" or the "second man" (1 Corinthians 15:45, 47), who provides a righteousness better than what we lost in Adam, then Jesus is the one and only remedy for the divine judgment of condemnation that rests on every human soul. This means he is a great Savior able to save persons from all times and all places and all peoples.The Nature of Justification
Through this comparison, Paul clarifies the nature of justification. Just as we were "made sinners" through Adam's disobedience not by infusing sin into our nature first but by imputing his sin to us, so we are "made righteous" through Christ's obedience not by an infusion of righteousness into our character but by the imputation of Christ's righteousness to us (Romans 5:19). This is why our justification is not based onOur righteousness and justification in Christ Jesus
The declaration of righteousness is best understood in "Paul's gospel." The apostle gives one of the most comprehensive explanations of our righteousness, which is central to the gospel, in his letters to the Galatians and the one of the most comprehensive explanations of our righteousness {justification} at the heart of the Gospel in his letters to the Galatians and Romans.The great transition: "But now"
Paul declares in Romans 3:21 that "now the righteousness of God apart from the law is revealed". These words mark one of Scripture's most glorious transitions—from humanity's hopeless condemnation to God's gracious justification.The law points out sin, but it cannot save us. But God has prepared us a plan: he created and brought us a righteousness that will save us, apart from the law, apart from our own earning and deserving, apart from our own merits.
Righteousness Through Faith, Not By Faith
The righteousness of God is not ours by faith; it is ours through faith. This distinction is crucial. We do not earn righteousness by our faith—we receive righteousness through faith in Jesus Christ. Faith is not a merit that earns salvation; it is merely the open hand that receives the gift God freely offers.The Divine Exchange
God's solution to our sin and condemnation is magnificent: He sent His Son Jesus to die for our sin and to give us His own righteousness when we trust in His Son. This is propitiation for Sin but sg. much more also! The guilty sentence is transformed into a sentence of justified, and justified by faith. God laid upon the spotless Savior the sin of the guilty, then took the righteousness from the innocent Savior and put it to the account of once-guilty sinners. {good heritage} Abraham, our forefather in faith provides the supreme Old Testament example—his righteousness did not come from performing good works, but from belief in God. Genesis 15:6 declares thatOur best efforts fall infinitely short
Israel had zeal for God, but they sought to establish their own righteousness and have not submitted to the righteousness of God.
For through the Spirit, by faith, we ourselves eagerly wait for the hope of righteousness.

Chapter 3: Jesus Has a Prophetic Message in the New Testament
The New Testament highlights the fulfillment of God's saving promises in the Old Testament, but it particularly stresses that those promises and covenants are realized through his Son, Jesus the Christ.Who is Jesus According to the New Testament?
According to the New Testament, Jesus is the new and better Moses, declaring God's word as the sovereign interpreter of the Mosaic law (Matthew 5:17-48; Hebrews 3:1-6). Where Moses mediated the old covenant from Mount Sinai, Jesus authoritatively reinterprets, (moreover) fulfills the Law from the mountain in Galilee, repeatedly saying, "You have heard that it was said... but I say to you." Jesus is the new Joshua who gives final rest to his people (Hebrews 3:7-4:13). Just as Joshua led Israel into the promised land of Canaan, Jesus leads his people into the ultimate rest - not a geographical territory but a spiritual reality of peace with God. He is the true wisdom of God, fulfilling and transcending wisdom themes from the Old Testament (Colossians 2:1-3). While Old Testament wisdom literature pointed to the fear of the Lord asThe Divine Authority of Christ
Jesus' miracles, healings, and authority over demons indicate that the promises of the kingdom are fulfilled in him (Matthew 12:28). His miracles also indicate that he shares God's authority and is himself divine, for only the Creator-Lord can walk on water and calm the sea (Matthew 8:23-27; compare Psalm 107:29). Jesus is the Messiah, who brings to realization the promise that One would sit on David's throne forever. Yet his messiahship transcends political expectations. He is the Son of Man who will receive the kingdom from the Ancient of Days (Daniel 7:13-14) and will reign forever. His reign, however, has been realized through suffering, for he is also the servant of the Lord who has atoned for the sins of his people (Isaiah 52:13-53:12; Mark 14:24; Romans 4:25; 1 Peter 2:21-25).The Divine Nature of Christ
Jesus is the image of God (Colossians 1:15; see Hebrews 1:3), existing in the very form of God, and equal to God. Yet he temporarily surrendered some of the privileges of deity by being clothed with humanity so that human beings could be saved (Philippians 2:6-8). This is the great mystery of the incarnation: fully God and fully man, united in one person. Jesus as the Son of God enjoys a unique and eternal relationship with God (Matthew 28:18; John 20:31; Romans 8:32), and he is worshiped just as the Father is (Revelation 4-5). His majestic stature is memorialized by a meal celebrated in his memory (Mark 14:22-25) and by people being baptized in his name (Acts 2:38; 10:48). In numerous texts, Jesus is specifically called "God" (John 1:1, 18; 20:28; Romans 9:5; Titus 2:13; Hebrews 1:8; 2 Peter 1:1). These declarations are not metaphorical or honorary titles, but statements of ontological reality - Jesus is God in human flesh.Chapter 4: Christ's Work on the Cross
The New Testament particularly focuses on Jesus' work on the cross, by which he redeemed and saved his people. The narrative of Jesus' suffering and death consumes a significant amount of space in the Gospels. It is the culmination of each of their story lines, indicating that the cross and resurrection are the main point of the story. In Acts we see the growth of the church and the expansion of the mission, as the apostles and others proclaim the crucified and resurrected Lord. The Epistles explain the significance of Jesus' work on the cross and his resurrection, so that believers are enabled to grasp the height, depth, breadth, and width of the love of God (Romans 8:39). Various themes woven together - creation, adoption, forgiveness of sins, justification, reconciliation, redemption, sanctification, and propitiation - teach that salvation comes from the Lord, and that Jesus as the Christ has redeemed his people from the guilt and bondage of sin. The cross represents the place where divine justice and divine mercy meet. There, the holy wrath of God against sin was fully satisfied, and the boundless love of God for sinners was fully displayed. Jesus bore sins not his own, suffered for sins that others had done, so that they could be free from sins.Chapter 5: Christ Is the High Priest, Mediator, and Sacrifice
1. Jesus as High Priest
The book of Hebrews develops the theme of Jesus as our Great High Priest more fully than any other New Testament book. This priesthood is not according to the order of Aaron, but according to the order of Melchizedek - a priesthood that predates and supersedes the Levitical system. Every high priest is appointed from among men to represent them before God, offering gifts and sacrifices for sins (Hebrews 5:1). The high priest must be able to sympathize with human weakness, having himself experienced temptation and struggle. Jesus perfectly fulfills this requirement, for though he was without sin, he was2. Jesus as Priestly Mediator
Jesus serves as the Mediator of a better covenant, one established on better promises (Hebrews 8:6). The Greek word for mediator (mesites) means "one who stands in the middle between two people and brings them together." Moses was the mediator of the Old Covenant, bringing the two parties together at Sinai. But Jesus is the Mediator of the New Covenant, a better covenant, bringing us to God the Father. Jesus' ministry as our High Priest takes place not in an earthly tabernacle or temple, but in the heavenly temple itself - the3. Jesus as Ultimate Sacrifice
With his own blood—not the blood of goats and calves—he entered the Most Holy Place once for all time and secured (obtained) our redemption forever (Hebrews 9:12 NLT). The sacrifices of the Old Covenant could never perfect the worshipers, being merely external regulations pointing forward to the reality that would come in Christ. The blood of bulls and goats could sanctify for the purifying of the flesh, butThe earthly Tabernacle and Temple had beautiful furnishings but no place for the priests to sit down, because their work was never finished. In contrast, Jesus
Chapter 6: His Earthly Work
Chapter 6.1: Christ's Work Before the Cross
Introduction: The Purpose of Jesus' Earthly Ministry
Before Jesus accomplished the definitive work of redemption on the cross, he engaged in an extraordinary three-year public ministry that revealed the character of God, proclaimed the kingdom of heaven, and demonstrated divine power over every form of human suffering and spiritual bondage. This ministry was not merely preparatory to the cross—it was integral to revealing who Jesus was and what he came to accomplish. Jesus' earthly ministry began around age 30, following his baptism by John the Baptist in the Jordan River. Luke records thatteaching, preaching, casting out demons, and healing.
Yet all these activities pointed toward a single, unified purpose—to reveal the kingdom of God and prepare humanity for the ultimate sacrifice that would reconcile sinners to their Creator.
1. The Teaching Ministry of Jesus
The Authority of His Teaching
From the very beginning of his public work, people recognized something radically different about the way Jesus taught. After teaching in the Capernaum synagogue, the crowdsThe Sermon on the Mount: Declaration of the Kingdom
The Sermon on the Mount, recorded in Matthew chapters 5-7, stands as perhaps the most comprehensive and systematic presentation of Jesus' ethical teaching. It has been rightly called Jesus' "Declaration of the Kingdom"—a manifesto of what life looks like when Jesus reigns as King in human hearts. The sermon begins with the Beatitudes, which overturn worldly values and announce blessing upon those the world considers weak or insignificant: the poor in spirit, those who mourn, the meek, those who hunger for righteousness, the merciful, the pure in heart, the peacemakers, and the persecuted. As Guzik observes, "The first word of this opening sermon of the ministry of Jesus is Blessed. Sin has cursed the earth... Yet if we will listen, Jesus shows us a better way—a blessed way." The word translated "blessed" conveys a happiness that has "its secret within itself, that joy which is serene and untouchable, and self-contained, that joy which is completely independent of all the chances and changes of life." This is not superficial happiness dependent on circumstances, but deep joy rooted in relationship with God. Throughout the sermon, Jesus repeatedly contrasts his teaching with common misunderstandings:The Pharisees had reduced God's Law to a system of rules that could be kept externally while the heart remained unchanged. Jesus called for transformation from the inside out. He wasn't abolishing the Law but fulfilling it, revealing its true spiritual depth and demanding a righteousness that exceeds mere external compliance. The Sermon on the Mount covers every aspect of life: anger, lust, marriage, oaths, retaliation, love for enemies, giving, prayer, fasting, materialism, anxiety, judging others, and perseverance in faith. It presents "a radically different agenda than what the nation of Israel expected from the Messiah. It does not present the political or material blessings of the Messiah's reign" (Guzik). Instead, it expresses the spiritual implications of Jesus' rule in human lives. Importantly, the sermon was addressed to Jesus' disciples, though the crowds also heard it. This teaching was meant for those who had committed to follow Jesus, showing them how to live as citizens of God's kingdom. Yet it also served as a call to the crowds—the "fence-sitters" who had not yet decided to follow Jesus—confronting them with the radical demands of discipleship.
The Content: Teaching Through Parables
Beyond the Sermon on the Mount, Jesus regularly taught using parables—earthly stories with heavenly meanings. These simple narratives about farmers, seeds, treasure, pearls, fishing nets, and household management contained profound spiritual truths about the kingdom of God. The parables served multiple purposes. They revealed truth to those "with ears to hear" while concealing it from those who had hardened their hearts. They were memorable, allowing Jesus' teaching to take root in the minds and hearts of his hearers. They also challenged assumptions and provoked thought, forcing listeners to wrestle with their meaning. Jesus explained to his disciples,Training the Disciples
A significant portion of Jesus' teaching focused on training the Twelve apostles who would carry on his mission after his ascension. As Guzik notes, "We can also regard this as Jesus training the disciples in the message He wanted them to carry to others. It was His message, meant to be passed onto and through them." Jesus taught them about the cost of discipleship, warning them of the difficulties:
A new commandment I give to you, that you love one another:
just as I have loved you, you also are to love one another.
By this all people will know that you are my disciples, if you have love for one another.”
Jn 13:34-35
just as I have loved you, you also are to love one another.
By this all people will know that you are my disciples, if you have love for one another.”
Jn 13:34-35
2. The Miracle Ministry of Jesus
The Purpose of Miracles
The Gospel of John records thatThe miracles were not random displays of power or mere acts of compassion (though compassion was certainly present). They had a specific theological purpose: to authenticate Jesus' identity as the Messiah and to confirm his message about the kingdom of God. Jesus himself declared,
Categories of Miracles
Jesus' miracles demonstrated his authority over every realm of creation and every form of human suffering: Authority Over Nature: Jesus calmed storms, walked on water, multiplied loaves and fish, and turned water into wine. These miracles revealed that the Creator himself had entered his creation. Only God could command the wind and waves to obey, yetThe Compassion Behind the Miracles
While miracles served to authenticate Jesus' message, they were never performed coldly or mechanically. They flowed from Jesus' deep compassion for suffering humanity. Matthew records,The Greater Healing: Forgiveness of Sins
Yet even in his miracle ministry, Jesus revealed that physical healing, though wonderful, was not the ultimate need. As David Guzik puts it, "The greatest need for the paralytic was not the revival of his limbs, but the renewal of his soul. And this restoration came not through the healing that was to follow, but through the knowledge that his sin was forgiven." Jesus gave the man something better than physical healing—he gave him spiritual rebirth, peace with God, and the assurance of being called God's son. Jesus did heal the man's legs—but only after forgiving his sins, to prove that he had authority on earth to forgive sins. The physical miracle authenticated the greater spiritual miracle. This pattern reveals Jesus' priorities: he cares about our bodies and our physical suffering, but he cares even more about our souls and our eternal destiny.I
