God is in Control

Many people are angry, and rightly so. Anger is a legitimate and proper response to injustice. Confronted with hardness of heart on the part of religious leaders, Jesus “looked around at them in anger” (Mark 3:5). David wrote, “God is a righteous judge, who expresses his wrath every day” (Psalm 7:11). Those who are angry with injustice on the basis of principle and conviction have often bettered our world. Luther was angry at religious abuses; Wilberforce was angry at slavery; Martin Luther King was angry at racism. They illustrate that anger, properly channeled and controlled, can produce positive action.

But there is a warning, “In your anger, do not sin” (Ephesians 4:26). Anger can turn to resentment and bitterness, which like a cancer, pollutes the soul. This is why the Bible warns that we are not to take vengeance on our enemies, “Do not repay anyone for evil… Do not take revenge, my friends, but leave room for God’s wrath, for it is written, ‘It is mine to avenge; I will repay’ says the Lord” (Romans 12:17,19)
