When we are upset or wronged, one of the most dangerous things we can do is stuff down our resentment, anger, and hostility. This causes unforgiveness to grow and fester in our hearts. Also, it is an act of rebellion to willfully refuse to give up one’s resentment and right to get even. Unforgiveness doesn’t fit in the life of a Christian. Therefore, we must make a decision to let go of resentment and unforgiveness.
When we deal with our unforgiveness, we will begin to see people through God’s eyes. Our attitudes will change, and we will be able to accept people as they are. Then, not only will we have strong, healthy bonds with others, but also a growing, loving relationship with our heavenly Father.
Forgiveness is an act of the will more than an act of the heart. Often people don't feel like being merciful to someone who has wronged them. But a resentful spirit grows into a terrible burden. The Lord knows that forgiveness is best, even when it is difficult.
