"There is a way which seems right to a man, but its end is the way of death. He who is slow to anger is better than the mighty, and he who rules his spirit, then he who captures a city." -Proverbs 16:25,32 NASB This is an issue of control. It is an issue of whether or not you have control over your emotion. With God's grace and our work, we need to control our anger and emotion.
Do not allow your anger and your emotion to be out of your control to points where you start thinking and saying things like, "I just get this way some times" or "I do not know how I got to this point" or "I just can't help it". THESE are points you are out of control.
Be very careful when something SEEMS or FEELS like it is right or good. Our feelings are undoubtedly fickle. They can (and DO) often lead us astray. Be careful in those moments when things just FEEL right.
Check these emotional moments, thoughts, and feelings. Check them with wiser people in your life. Check them with God's Word. "He who gives attention to the word will find good and blessed is he who trusts in the Lord." (vs 20)
When we are out of control with our anger and other emotions, it is because something in our broken heart actually believes (or FEELS) like that is the best reaction.
Our hearts are fickle, deceptive, and destructive when they are not constantly entangled and in-check with God's Word and Heart.
