I once helped a woman who was deeply hurt by someone close. Her unforgiveness kept her from making spiritual progress, and the devil often triggered anger in her because she didn’t let the offenses go.
It’s very important as Christians that we allow God to heal of us of the things people do to hurt us. We may think we have a right to hold on to it and be angry, but as long as we do that it will continue to hinder our walk with God.
The Bible says:
Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice. (Ephesians 4:31 NIV)
Don’t spend time re-playing over and over what the person did. Don’t even say negative things about them. Instead, bring your burden to God. It may feel impossible now, but with prayer God can help you forgive and heal.
Choosing to let go will bring peace and close the door to the devil!
