God can touch the hearts of the people that you have offended but find it hard to get their forgiveness. Say this prayer in faith
Father, I know that I am wrong in acting on what I have said or done wrongly to this person (state what you did) but I have repented from my heart. I pray that this person's (mention his/her name) heart is enlarged to be able to forgive me and let go of the incident.
Father, I pray that this heart is healed from whatever hurt I have deliberately or in deliberately caused it. Let your love fill his heart so that he is not set on revenge. I ask that there be more love and peace shared among us than ever before.
