This prayer is powerful to help a beloved one you know to be willing to let go of wrongs. Pray with faith in your heart:
Dear Lord, I pray for this person (mention the name) that his heart is opened to allow the influence of Your Spirit upon his heart such that he is filled with Your graciousness and love. I ask that he finds it easier to let go of hurts, disappointments, and betrayals from people.
Father, I ask if he is much wiser in his relationships and discerning as well. Set his heart free Lord, of every form of anger or bitterness or lingering unforgiveness. May he be an example of Your Word and let Your will be done in his life forever. Amen.
