What is self-control? 

Proverbs 16:32 He who is slow to anger is better than the mighty, And he who rules his spirit, than he who captures a city.; 25:28 Like a city that is broken into and without walls Is a man who has no control over his spirit.;

I Corinthians 9:27 but I discipline my body and make it my slave, so that, after I have preached to others, I myself will not be disqualified.; 13:4-7 Love is patient, love is kind and is not jealous; love does not brag and is not arrogant,does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered,does not rejoice in unrighteousness, but rejoices with the truth;bears all things, believes all things, hopes all things, endures all things.

II Corinthians 10:3-5; For though we walk in the flesh, we do not war according to the flesh,for the weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses.for the weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses.

I Peter 2:11-12.Beloved, I urge you as aliens and strangers to abstain from fleshly lusts which wage war against the soul Keep your behavior excellent among the Gentiles, so that in the thing in which they slander you as evildoers, they may because of your good deeds, as they observe them, glorify God in the day of visitation.

What Self-Control Means

In Galatians 5:23  gentleness, self-control; against such things there is no law.

"self-control" is the translation of the Greek wordenkrateia, which means "possessing power, strong, having mastery or possession of, continent, self-controlled" 

Self-control is comprehensive in practical application to life, but the Bible does not use the word extensively. It is implied, however, in many exhortations to obedience, submission and sinless living. The noun form is used only three times, the verb form twice (I Corinthians 7:9; 9:25) and the adjective form once (Titus 1:8 but hospitable, loving what is good, sensible, just, devout, self-controlled, ). 

The negative form of the adjective is used three times. 

In II Timothy 3:3 unloving, irreconcilable, malicious gossips, without self-control, brutal, haters of good, it is translated "without self-control " in Matthew 23:25 "Woe to you, scribes and Pharisees, hypocrites! For you clean the outside of the cup and of the dish, but inside they are full of robbery and self-indulgence, "self-indulgent"; 

and in I Corinthians 7:5 Stop depriving one another, except by agreement for a time, so that you may devote yourselves to prayer, and come together again so that Satan will not tempt you because of your lack of self-control.

What commonly shows a lack of self-control?Proverbs 23:19-21, 29-35; I Thessalonians 4:3-5 that each of you know how to possess his own vessel in sanctification and honor,not in lustful passion, like the Gentiles who do not know God;

II Timothy 3:1-5

.But realize this, that in the last days difficult times will come.For men will be lovers of self, lovers of money, boastful, arrogant, revilers, disobedient to parents, ungrateful, unholy,unloving, irreconcilable, malicious gossips, without self-control, brutal, haters of good,unloving, irreconcilable, malicious gossips, without self-control, brutal, haters of good,unloving, irreconcilable, malicious gossips, without self-control, brutal, haters of good,

We see a good example of self-control implied in Proverbs 25:28: "Whoever has no rule over his own spirit is like a city broken down, without walls." No specific Hebrew word in this sentence means "self-control," but "rule" certainly implies it

Is self-control for the benefit of self alone? Romans 12:18-21; 13:8-14; 14:7-10, 20-23.
