Prayer is the open admission that without Christ we can do nothing. And prayer is the turning away from ourselves to God in the confidence that He will provide the help we need. Prayer humbles us as needy and exalts God as wealthy
John PiperThe point is not that the resurrection is the price paid for our sins. The point point is that the resurrection proves the death of Jesus is an all-sufficient price. If Jesus did not rise from the dead, then his death was a failure, God did not vindicate his sin-bearing achievement, and we are still in our sins.
John Piper
