Our obedience is God's pleasure when it proves that God is our treasure. This is good news, because it means very simply that the command to obey is the command to be happy in God. The commandments of God are only as hard to obey as the promises of God are hard to believe. The Word of God is only as hard to obey as the beauty of God is hard to cherish.
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 PiperGod's greatest interest is to glorify the wealth of His grace by making sinners happy in Him.
John Piper
