Prevailing Prayer
The two first and essential means of grace are the Word of God and prayer. Conversion comes through these, for we are born again through the living and enduring(abiding) word of God  (1 Peter 1:23), and whoever will call on the name of the Lord will be saved  (Romans 10:13). By the Word of God and prayer, we also grow. Scripture tells us we should desire, or crave, the pure spiritual milk  of the Word so we may grow by it (1 Peter 2:2), and we cannot grow in grace and in the knowledge of the Lord Jesus Christ unless we also speak to him in prayer. 
  
from Him and through Him and to Him are all things  (Romans 11:36), and it is only by hearing God’s Word,  where we learn his purposes toward us and toward the world, that we can pray acceptably. This means praying in the Holy Spirit and asking the things which are pleasing in his sight.
