Bitterness harms us. We think it harms the person we are bitter toward but the joke is on us. Our bitterness rarely impacts the recipient of our bitterness. Most likely, they don't even know we are bitter toward them and if we try hard to make sure that they know we are bitter, it becomes even worse for us. In contrast, forgiveness makes us better. Forgiveness may not feel better at the time but most things worth having don't feel good at the time. Working out may not feel good at the time, but the results make us feel good afterwards. Bitterness is a selfish act of momentary satisfaction.
Lord, help me to be better and being less bitter and selfish in how I relate to others.
