‘A shortsighted fool still loses his patience and shows his wrath, but a wise mind [exercises self-control and] keeps it out,' according to the Bible. Rage can be expressed openly or silently. When you use silence as a tool to hurt others, you're engaging in juvenile immaturity and emotional coercion.
Do you recall thinking, "I'm not talking to you anymore," when someone declined to do what you wished when you were a kid? That may be appropriate behaviour for an infant, but it is not acceptable behaviour for those who are called to spiritual maturity. If you have a tendency to lose your patience on a regular basis, consider the following Scriptures:
(1) ‘Better…one with self-control than one who takes a city.’ (Proverbs 16:32 NIV)
(2) ‘A person’s wisdom yields patience; it is to one’s glory to overlook an offence.’ (Proverbs 19:11 NIV)
(3) ‘Do not be quickly provoked in your spirit, for anger resides in the lap of fools.’ (Ecclesiastes 7:9 NIV)
(4) ‘Be quick to listen, slow to speak and slow to become angry, because human anger does not produce the righteousness that God desires.’ (James 1:19–20 NIV)
So, pray to God to help you restrain your anger. Remember that rage is like fire: when it's under control, it's like a raging fire that attracts people to a cause you care for. When it loses power, though, it has the potential to kill anything in its way.
