Ask God for His help in being patient. Ask God for His help in reasoning things out. Once the words are out of our mouths it is impossible to take them back.

Anger then tends to have a snowballing effect.
It seems that many times, once we are angered, we very rapidly lose control of the anger and become less and less tolerant of everybody and everything. This is a real tragedy because it makes for a really carnal believer. We hear the word of God and yet willfully continue to dishonor God by gratifying our own desires. There are saved people who gather a lot of Scriptural knowledge but do not allow the Holy Spirit to use that knowledge to God's glory. They then use this knowledge as either a toy or as a weapon.
