From a biblical perspective, self-control is about gaining mastery over your body and bringing it under submission to God. “Therefore do not let sin reign in your mortal body so that you obey its lusts, and do not go on presenting the members of your body to sin as instruments of unrighteousness; but present yourselves to God as those alive from the dead, and your members as instruments of righteousness to God” (Romans 6:12). It’s a matter of ignoring the desires of your flesh and disciplining yourself for the purpose of righteousness.
There are two key aspects to gaining that mastery over your body. The first is to feed on the riches of Scripture. Consistent, faithful study of God’s Word stimulates your spiritual growth, sharpens your mind, and strengthens you against temptation. Train yourself to think and live biblically, and you’ll find it increasingly easier to turn away from temptation. “But I say, walk by the Spirit, and you will not carry out the desire of the flesh” (Galatians 5:16).
The second aspect of gaining mastery over your body is starving yourself of opportunities to sin. You know what triggers temptation in you—avoid those people, places, and things at all costs. It does you no good to develop positive patterns if you continue to expose yourself to all kinds of input that corrupts your thinking. You can’t afford to toy with your desires and emotions—you’ve got to flee temptation and never look back.

Because the God of the Bible is not a god who comes to indulge us. He is a God who makes demands upon us. He is the God [speaking] when Jesus turns to His disciples and says If you want to be serious about Christian living, take up your cross, die to your “self”, lose the world, gain your soul, shame now, honor later.
It’s a radical message! Here’s something worth living for! Here’s something worth dying for!
