Take time today to see where you are still holding yourself hostage by not forgiving. Yes, you are the one being held hostage, not the other person, place, or thing. Unforgiveness only hurts you. Allow Holy Spirit to show you a place of Unforgiveness and then realize how you feel about that place. Then give that to the Lord. How? You may need to lament or grieve, but let it go.
Remember the goal here is to remain fluid, flexible so that life cannot break you. Go ahead, start today. enough for now.
