His clear cut call to really understanding the true nature of Christian life is that it must be lived in prayer. He shows from the beginning of the bible to the end God has gathered apart a people to Himself that would 'call upon His name'. Be challanged, convicted and changed as you listen to this message, it has been a turning point for my life and many others also that I personally know. I believe this message was preached at Jack Hayford's church. The quality isn't the best and the second half of the sermon is missing but its worth the listen.
