Repentance is a change of thought and action to correct a wrong/sin and gain forgiveness, referring to confession to God, ceasing sin against God, and resolving to live according to Gods law. It typically includes an admission of guilt, a promise or resolve not to repeat the offense/sin
Acts 3:19 (NIV) "Repent, then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord."
Repentance is a complete change of mind and living, when we repent our sins to God i.e. ask for forgiveness for all our sins we are openly asking for God to change our heart and whole being. Thinking differently
And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
Jeremiah 17: 14 Heal me, O LORD; and I shall be healed, save me; and I shall be saved: for thou art my praise. :hands:
