Not Just

Forgiveness is not just, "I forgive you." It's a prayerful "removal" of the "injury" as far as the east is from the west. It's a deepest sea burial of the anger and resentment. It's a trust in God to use all things for His glory. It's a confidence that He is on the throne. It's removing the words, "What, again!" from one's vocabulary and mindset.
It's forgiving as He forgave you.
