For a Christian to defy adversities is to "despise" chastisement. Instead of hardening himself to endure stoically, there should be a melting of the heart.
If the believer sins after he is saved, God will chastise him. But the chastisement is not payment for sin. Jesus Christ paid for our sins two thousand years ago when He died on the cross.
God never punishes his children in the sense of avenging justice. He chastens as a father does his child, but he never punishes his redeemed as a judge does a criminal. It is unjust to exact punishment from redeemed souls since Christ has been punished in their place. How shall the Lord punish twice for one offense?
