"And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you."
Forgiveness is not pretending it did not hurt. It is choosing to release the debt, because a far greater debt has been released for us.
Unforgiveness is like drinking poison and waiting for the other person to fall sick. As you remember how much God has forgiven you, ask Him for the grace to let someone else go free.
Prayer
Father, You have forgiven me so much. Give me a tender heart, and the grace to forgive those who have hurt me. Amen.
Today's step
Ask God to bring one person to mind whom you need to forgive, and pray a blessing over them.
