Forgiveness costs us nothing. All our costly obedience is the fruit, not the root, of being forgiven. That's why we call it grace.
John PiperThis is the centre of the gospel - this is what the Garden of Gethsemane and Good Friday are all about - that God has done astonishing and costly things to draw us near.
John PiperFaith stands or falls on the truth that the future with God is more satisfying than the one promised by sin. Where this truth is embraced and God is cherished above all, the power of sin is broken. The power of sin is the power of deceit. Sin has power through promising a false future. In temptation sin comes to us and says: "The future with God on his narrow way is hard and unhappy, but the way I promise is pleasant and satisfying." The power of sin is in the power of this lie.
