The solution to the suffering brought by divine discipline is immediate confession of sin. As soon as a sin is confessed, it is forgiven, and the believer is completely cleansed. By confessing our sins to God, we admit our disobedience. His policy is one of grace. That means that He forgives freely from His own goodness and for His own glory on the basis of what Christ did for us on the cross, not on the basis of any works which we might attempt to do as penance.
Confession of sin is a sine qua non in the Christian way of life.
Let us therefore not allow unconfessed sin or inordinate guilt about past sin to stand in our way.
