1 Cor 15:10

15:10 the grace of God. Having freely admitted the abnormal and undeserving character of his experience, Paul moves on to stress that his past life is no reason to reject his message. Where sin abounds, God’s effectual grace abounds all the more (Rom. 5:20); where we are weak, God’s grace is strong (2 Cor. 12:9, 10). Divine grace did not make Paul lazy, but caused him to labor “harder” than anyone else.
