Repentance is not one time action, but it’s an ongoing decision and action to turn to God and do things His way. This involves areas in our thinking that are not visible, but could eventually have an impact in our actions.

Repent, then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord. Acts 3:19

Whoever conceals their sins does not prosper, but the one who confesses and renounces them finds mercy. Proverbs 28:13
