How to deal with anger in a proper way.
When someone says something that makes you angry, it may be best not to say anything. If you do speak, the best answer is usually one that will cool the emotions of both parties. Proverbs 15:1 says, "A soft answer turns away wrath, but a harsh word stirs up anger." Verse 18 goes on to say, "A wrathful man stirs up strife, but he who is slow to anger allays contention." We all need to control our anger despite of what others may say or do to offend us.
One of the fruits of God's Spirit is self-control (Galatians 5:23). We have to be tolerant of others, always willing to forgive. Don't let the sun go down on your wrath (Ephesians 4:26). In other words, don't harbor grudges that could develop into a harmful attitude of bitterness.
In order to act in a manner pleasing to God, we can pray to God, asking for His help. If we do our part to honor Him, God promises to help us (Matthew 21:22; John 14:13).
