Hebrews 12:15 as found in the New Testament of the Bible:
“See to it that no one misses the grace of God and that no bitter root grows up to cause trouble and defile many.”
Really? Bitterness can cause us to miss the grace of God? Bitterness only causes trouble for yourself and others, and defiles you. Bitterness comes from you thinking of yourself more highly than you ought (Romans 12:3), and forgetting that all have sinned and come short of the glory of God (Romans 3:23). Bitterness leads to either bullying or shunning, and ends in broken relationships and a cancer of the heart. It can cost us our eternal salvation.
The opposite of bitterness is forgiveness. Forgiveness does not mean you condone what someone else has done. It means you let go of it and let God handle it. It means you wish the best for the offending person or situation. You can wish even the most hardened criminal will someday turn to God and turn his life around. How many times in your lifetime have you asked God to forgive you for the same things over and over? God forgives you as you forgive others.
Forgiveness lifts weights off of you until you feel as though you could soar. Forgiveness takes the clouds away and brings back the sunshine. Forgiveness makes sure you do not miss the grace of God.
