It's the lifting of a heavy burden. Forgiveness is the key that unlocks the door of resentment and the handcuffs of hatred. It is the supernatural power that breaks the chains of bitterness. Forgiveness demands change. Forgiveness is not soft hearted, mush-mouth foolishness.
Forgiveness is full of compassion, but it demands a change in the character.
To forgive someone without demanding that they change is to make the grace of God and accomplice to evil. He expected her to change. Forgiveness is not earned, it is accepted. Because you are responsible. God is extending to you today amazing grace, that can save you, and heal you, and give you joy unspeakable and full of glory.
