'Self control' in the Bible

Do not deprive each other, except by mutual agreement for a specified time, so that you may devote yourselves to prayer. Then resume your relationship, so that Satan may not tempt you because of your lack of self-control.

But if they do not have self-control, let them get married. For it is better to marry than to burn with sexual desire.

Each competitor must exercise self-control in everything. They do it to receive a perishable crown, but we an imperishable one.
