Self control is a fruit of the HolySpirit.
Galatians 5:16-26
16*So I advise you to live according to your new life in the Holy Spirit. Then you won’t be doing what your sinful nature craves. 17*The old sinful nature loves to do evil, which is just opposite from what the Holy Spirit wants. And the Spirit gives us desires that are opposite from what the sinful nature desires. These two forces are constantly fighting each other, and your choices are never free from this conflict. 18*But when you are directed by the Holy Spirit, you are no longer subject to the law.
19*When you follow the desires of your sinful nature, your lives will produce these evil results: sexual immorality, impure thoughts, eagerness for lustful pleasure, 20 idolatry, participation in demonic activities, hostility, quarreling, jealousy, outbursts of anger, selfish ambition, divisions, the feeling that everyone is wrong except those in your own little group, 21*envy, drunkenness, wild parties, and other kinds of sin. Let me tell you again, as I have before, that anyone living that sort of life will not inherit the Kingdom of God.
22*But when the Holy Spirit controls our lives, he will produce this kind of fruit in us: love, joy, peace, patience, kindness, goodness, faithfulness, 23*gentleness, and self-control. Here there is no conflict with the law.
24*Those who belong to Christ Jesus have nailed the passions and desires of their sinful nature to his cross and crucified them there. 25*If we are living now by the Holy Spirit, let us follow the Holy Spirit’s leading in every part of our lives. 26*Let us not become conceited, or irritate one another, or be jealous of one another.
Dying to self through bearing the cross is the key to allowing God to work within. Becoming one who is led by the Holy Spirit is not learned behavior as so many think. It is becoming intimately involved with the Holy Spirit and heeding His instructions.
Ephesians 3:14-21
14*When I think of the wisdom and scope of God’s plan, I fall to my knees and pray to the Father,* 15*the Creator of everything in heaven and on earth. 16*I pray that from his glorious, unlimited resources he will give you mighty inner strength through his Holy Spirit. 17*And I pray that Christ will be more and more at home in your hearts as you trust in him. May your roots go down deep into the soil of God’s marvelous love. 18*And may you have the power to understand, as all God’s people should, how wide, how long, how high, and how deep his love really is. 19*May you experience the love of Christ, though it is so great you will never fully understand it. Then you will be filled with the fullness of life and power that comes from God.
20*Now glory be to God! By his mighty power at work within us, he is able to accomplish infinitely more than we would ever dare to ask or hope. 21*May he be given glory in the church and in Christ Jesus forever and ever through endless ages. Amen.
