Men who are easily angered cannot role model the love. Anger that is not under strict self-control has great destructive potential. There is such a thing called righteous indignation which Jesus Christ Himself manifested when He cleansed the temple and yet He did not sin. Ephesians 4:26 says, "Be ye angry, and sin not: let not the sun go down upon your wrath: neither give place to the devil."
Anger is not a sin in itself. It is a sin when it gets out of control. There are many times God's sinless anger is manifested in Scripture.
Children should be role-modeled by fathers that are not easily provoked to anger. Children should not have to tip toe around their father lest the slightest infraction should start an avalanche of anger.
Anger has great potential for both wife abuse and child abuse. This abuse can be both verbal and physical. The truth is that both forms of anger are destructive and not acceptable. Both forms are ungodly and sinful. If a man cannot disciple his anger, no woman or child should be forced to suffer it. The father should seek serious counsel and, if this problem continues, no one should be bound to live with it.
I loathe separation, but I loathe abusive anger more. If you can't control your anger, you should live with it on your own. Why should others suffer?
Be encouraged.
