First of all, let’s talk about what forgiveness isn’t. It does not mean that you agree with an offense that hurt you or made you mad. It’s releasing that hurt out of your life. Holding on to offense is like protecting a festering wound. For some reason we tend to keep it fresh and painful. Why? Why? Why? Take it to God. Tell Him what hurts. It might help to visualize putting it in a box and handing it Him. Whenever it comes up again, give it to God. Ask Him to take it away. That event should become just a memory without any emotion attached to it. And if the same offence happens again? Forgive again. Seventy times seven. (Matt 18:22) Jesus said to forgive people as long as they need forgiving. It’s a bad thing to not forgive others. “But if you do not forgive men their trespasses, neither will your Father forgive your trespasses.” (Matt 6:15) Do you really want to live with that?
God also gives good things when we let go of bad things. It’s ok to ask for it. Tell Him, God I give you this pain and hurt. What do you have for me in exchange? He’s delighted to give you joy, peace, healing, a promotion, what ever He sees you need the most. Unforgiveness will keep doors closed that we desperately need open. Ask God to show you where you need to forgive and let go for good.
