What do you mean by repentance?

Repentance is a change of mind about sin, self, God, and Christ, which changes the attitude, which changes the actions. It involves not just the mind but the conscience. It is the sinner's acknowledgment of his ungodliness, lostness, helplessness, and hopelessness, and his need of grace. It is an about face. It is taking sides with God against one's self. It involves penitence, that is, sorrow for sin, but it is more than this. You can be sorry for sin and yet not turn away from it.
