The dictionary defines anger as "a strong feeling of displeasure and usually of antagonism." In the Old Testament, the Hebrew word for "anger" is also used for "nostrils," for when people are angry, their nostrils flare open and their breathing becomes heavy. In the New Testament, two primary words are translated as "anger": One refers to a passionate outburst, and the other, to a settled, irate frame of mind.

Ephesians 4:31 tells us that neither one is acceptable to God: "Let all bitterness, wrath, anger, clamor, and evil speaking, be put away from you, with all malice." In the same context appears a seemingly conflicting statement: "'Be angry, and do not sin': do not let the sun go down on your wrath" (verse 26). In Greek, this literally means "Be angry but do not sin," "In your anger, do not sin," or "When angry, do not sin."

Dr. Richard Strauss, the author of nine books and a minister of 21 years, writes in his book, Getting Along With Each Other, that some psychologists claim that it is good for people to vent their anger to release the pressure. The problem, he writes, is that venting tells the body to maintain an emergency status, keeping the anger flowing. This establishes more deeply the habit of reacting angrily, making it more difficult to overcome sinful anger, as the Bible instructs.

Further, allowing the emergency state to continue reduces our ability to reason clearly and ultimately upsets the body's chemical balance, making us physically sick. Doctors suggest that migraine headaches, thyroid malfunction, ulcerative colitis, toxic goiters, high blood pressure, ulcers, heart attacks, backaches, rheumatism, arthritis, allergies, indigestion, asthma, and many other illnesses can be emotionally induced. Jordan Rubin, the author of The Maker's Diet, states, "When we are angry, our immune system can be depressed for up to 6 hours."

How do we overcome sinful anger? First, by recognizing and admitting we have an anger problem and taking it to God, confessing it, and praying for His help. As with any sin, we must acknowledge it before God in all honesty, seeking His forgiveness and asking for strength to overcome it through His Spirit.

Second, we need to examine its causes. Some common causes are: 1) selfishness, that our selfish demands are not being met; 2) perfectionism, that our oftentimes unjustified expectations are not being satisfied; and 3) suspicion, that we misinterpret others' motives or intentions.

Third, we must "be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you" (Ephesians 4:32). Kindness is the counterpart of malice, a resentment that produces bitterness. Kindness produces goodness, helping us to avoid responding in anger.

Tender-heartedness is the opposite of cold-heartedness. A tenderhearted person, sensitive to the needs of others, is compassionate and merciful, loving justice and hating injustice and sin while showing love toward the sinner.

Forgiveness, like a healing medicine, is vital to unity and harmony among people. More often than not, it is more for the offended or hurt person because the offender may not care if he is forgiven or not. Forgiveness stops anger from settling in our minds, leading later to resentment and bitterness. Paul suggests that we need to practice forgiveness to learn from God's example.

In James 1:19-20, the apostle sums up what we need to know about anger: "So then, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath, for the wrath of man does not produce the righteousness of God."
