Proverbs 14:29 30 (NLT) – Those who control their anger have great understanding; those with a hasty temper will make mistakes. A relaxed attitude lengthens life; jealousy rots it away.
During a sparring match, if we allow ourselves to become angry, we will start to throw every technique at our opponent, completely exposing our weaknesses resulting in defeat. We will make plenty of mistakes, and it will see to our downfall. When you relax, you are able to discern and use strategy to take your opponent down.
This applies to our lives as well. If you become angry at your spouse, you may say harsh things and insults at her which could result in damaging your marriage. Yelling at your boss at work in anger could get you fired. Relax and be gentle in whatever circumstance you face. God is in control anyway.
