God said the following things through wise Solomon:
He who is slow to anger is better than the mighty, and he who rules his spirit, than he who captures a city. (Proverbs of Solomon 16:32)(NASB)
Self control identifies itself in conflict situation
It is easy to rule over your emotion when people treat you well and with respect. But, when conflict situations occur, when you are provoked to anger, then it is difficult to control yourself. He who controls himself will think better, calmly and will not be out of temper, because in this way, he will do wrong. He who controls himself is slow to anger and self control values more than courage and bravery. You will be able to overcome the most difficult life conflicts only by self control and wisdom from God.
Lack of self control makes you extremely vulnerable
Another Proverb from the Holy Book says:
Like a city that is broken into and without walls is a man who has no control over his spirit. (Proverbs of Solomon 25:28)(NASB)
This man will be easily provoked to anger and to unwittingly deeds, that will bring him ruin, shame and suffering.
Self control is a fruit of the Holy Spirit
You ask yourself how you can become a person who keeps his temper. Every person who believes in the Lord Jesus from all the heart and enters the covenant with Him, receives the Holy Spirit from God. Together with the Holy Spirit, God pours His love into our hearts, and we are also given spiritual gifts to serve other children of God and so, our characters are changed, as Apostle Paul writes:
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. Now those who belong to Christ Jesus have crucified the flesh with its passions and desires. (Galatians 5:22–24)(NASB)
Everyone who received the Holy Spirit can control himself, meaning that he is not provoked to anger and other bad emotions. The only responsibility of this man is to let himself be led by the Spirit of God, that lives in him, in every circumstance. God help us all to keep our temper and to pursue peace with all men.
