Lord, create in this man a clean heart and renew a right spirit within him. Show him where his attitude and thoughts are not what You would have them to be, especially toward his wife. Convict him when he is being unforgiving. Help him to let go of any anger, so that confusion will not have a place in his mind. Help him change his behavior, enable him to make changes that last. Enable him to be the head of his home and family. Renew this couple's love for one another. Heal their wounds. Give them patience, understanding, and compassion. Help them to be loving, tenderhearted, and courteous to each other. Bring them to a new place of unity with one another. Give them words that heal, not wound. Fill their heart with Your love so that it overflows through their speech. Convict his heart. Help him be the man and husband that You want him to be. In Jesus' name, Amen.
