The words of the preacher admonished that, ‘‘do not hasten in your spirit to be angry, for anger rests in the bosom of fools,’’ (Ecclesiastes 7:9, NKJV). The bible highlighted in different places the negative effect of anger amidst us humans because of its destructive nature. If the quoted scripture above says that, do not hasten in your spirit to be angry, then it means that anger is something that may rise up in us anytime due to the situations around us that we are not in agreement with, but we must master anger by being able to suppress it when it comes. The destruction that anger can cause if not mastered is such that can destroy relationships, raze down a nation and cause general havoc to the detriment of all.
If anger rests in the bosom of fools, then it means that people who are being controlled by anger are shortsighted and not taking thought of the great destruction their lack of control can cause. For example, some have been controlled by anger and they get killed in a fight, while the killer also rots away in jail. This reveals that for the offender and the person who is offended, anger takes a negative effect on both. And this is one of the reasons for laws in various countries so that the behaviors of people can be checkmated for people to be more civil.

As Christians, we must know that it is not impossible to curb anger, because we have the grace of God available to us to overcome sins, (Romans 6:14). Anger may become a sin when we entertain it continuously without giving way to forgiveness. When we are offended, we may get angry, because we are still humans with flesh and blood, but we must understand that we have the Spirit of God in us to give us calmness and act rightly, (Ephesians 4:26, 27, 31, NKJV). You would agree with me that the disciples of the Lord were offended when Jesus was rejected in a village of the Samaritans, and they beckoned on the Lord to send fire on the Samaritans as in the days of Elijah; but Jesus rebuked them, that they do not know the manner of spirit that they are made of, (Luke 9:55). The spirit that we have received from the Lord is not for destruction, but for construction; that is, we repair and build things by the Spirit and power of God that is in us, not destroy them.

Moreover, as children of light, we should learn to speak calmly and utter out good things from our mouth. This is able to build up things and as well deliver us from unknown dangers. If we allow gentleness which is one of the fruits of the Spirit to have way in us, we are sure to learn how to reply appropriately when talking to others, (Proverbs 15:1).
Even though the way of the Lord is not the way of the world, yet the teachings of God have all good and civil way of life because what the Lord has taught us is the culture of heaven.
