let the wicked forsake his way, and the unrighteous man his thoughts; let him return to the Lord, that he may have compassion on him, and to our God, for he will abundantly pardon. (Isaiah 55:7, ESV)
Forgiveness is a wonderful thing. We know that God freely forgives and forgets but what is our part? Repentance. That means turning our back on what once was, i.e. our evil ways and thoughts. Turn your back to your past and turn to the Lord who freely forgives.
Prayer: Lord, forgive my selfishness. I ask for your forgiveness.
