We've often been told that to hold a grudge is like drinking poison and expecting the other person to die. The easiest way to overcome someone who has wronged you, and acts like an enemy, is to make them your friend. It's the ultimate win, and to do that we must learn to forgive.
All wrong behavior is wrong! There is no excuse for it. The act of forgiveness never implies that any offense was accepted as proper behavior. When someone is wounded through the acts of another the offense is real and the emotional pain incurred is also real. We don't have the ability to let the offender off the hook, we cannot impose consequences or put stipulations on forgiveness. That burden is for God to handle, our load is lifted and we are emotionally free when we move the guilty from off our back to that of the God's
Forgiveness is the unconditional dismissal of debt and not a sign of spineless passivity. Your not a doormat if you find forgiveness in your heart, it's a sign of godly courage when you allow Him to handle the debt owed.
Remember, not forgiving someone give them a link that eternally binds you together. Neither are ever free from it. Unforgiveness becomes a heavy load we bear like a stack of bricks weighing us down. Neither party can be freed of the burden as long as the debt remains on your books. Clear the account and allow god to be the collection agency. He'll make those annoying conscience calls asking for payment and garnishing their soul. Remember to forgive is to release your rights regarding the offense.
