When you are enraged, look to God and ask Him, "Father, is Your blood boiling, too?" I don't think it is. The wrath of man does not work the righteousness of God. Remember the Apostle Paul when he was still called Saul. He was spiritually blind, mocking Jesus Christ and condemning Christians to their death. God put a stop to Saul (Paul) and turned his life around but it was in love not rage.
Perhaps you should ask the Lord what exactly is in your heart at the point where you become so angry. Pray that He reveal any hidden thing in your heart that you might know what your real motive is for being that angry. This always helps me see past my emotions. Hope it helps you, too.
