When someone has done you wrong, you have 2 choices: forgive them for they do not know what they are doing or forget what they have done and still live with the anger and resentment.
Forgiving someone is not done because they deserve it, it's done because you deserve it! When you are angry and resentful towards someone, you are allowing them to live in your head rent free.
Forgetting what someone has done is not learning a lesson from the situation. God allows us to endure the enemy's tests to strengthen us and rely on His strength and power. Trust in the Lord with all your heart and lean not on YOUR understanding...these words are empowering, yet at the same time creating a feeling of powerlessness. God has all the power and by admitting we need to rely on Him empowers us. Blessings-Tina
