In our study of how to please God through our whole life, we are beginning with the spirit – the part of us that is being renewed against the effects of sin. Those who are born again have a new nature that is fed through our devotion to prayer and reading God's Word.
One writer said, "Whatever causes us to pray is a good thing." The Bible is chock-full of examples of God's people praying to Him. In John 17, we read an example of Jesus Himself praying. Christ relied heavily on prayer to sustain His life and ministry. His prayer in this passage shows the purpose of His life. We too can find particular purpose for our lives by studying this prayer and praying similarly.
