Anger rages like a fire. It is destructive and can start major life fires. For the angry man or woman that daily deals with anger, frustrations gone wild and bitterness. These things wage war on their lives and the lives of others around them. Fires get started, fired that devour. When anger gets out of control and starts becoming deeply rooted it takes a persons character over. If un checked or dealt with, it also affects that persons health. Anger is simply not healthy fruit.
Wrath is cruel, and anger is outrageous; but who is able to stand before envy? Be not hasty in thy spirit to be angry: for anger resteth in the bosom of fools. He that is soon angry dealeth foolishly: and a man of wicked devices is hated. It is better to dwell in the wilderness, than with a contentious and an angry woman.
Anger is not a fruit of God's Spirit.
