Repentance is a deep sorrow for a past sin, evil action or wrongdoing. Repentance is regret for a past action.
Repentance begins when you admit your current condition. Repentance begins when you admit that you need help.
Face it; you have already surrendered to the brutal trap of addictions. You are enslaved by the substance which controls you. Now it is time to be delivered from the destructive grip of drug addiction. But, you can’t be delivered by your own will power. It requires a force much more powerful than your will (more about this at the Redemption Station).
The first condition is repentance, which means a change of mind. Formerly I thought sin a pleasant thing, but now I have changed my mind about it; formerly I thought the world an attractive place, but now I know better; formerly I regarded it a miserable business to be a Christian, but now I think differently. Once I thought certain things delightful, now I think them vile; once I thought other things utterly worthless, now I think them most precious. That is a change of mind, and that is repentance.
-Watchman Nee
Repentance occurs when you ask forgiveness of those whom you have wronged.
Repentance must be personal, sincere, honest and complete.
