The Bible advises avoiding sin by actively walking in the Spirit, studying Scripture, praying for strength, fleeing temptation rather than battling it, and renewing one's mind. Key strategies include setting no "provision for the flesh" (avoiding situations that tempt you), accountability with other believers, and relying on God's grace to transform desires. 
Key Biblical Methods to Avoid Sin:

  • Walk by the Spirit: Yielding to the Holy Spirit's guidance and strengthening, rather than gratifying sinful desires (Galatians 5:16).

  • Flee Temptation: Actively running away from sinful situations, especially sexual immorality and youthful lusts, rather than trying to withstand them (1 Corinthians 6:18, 2 Timothy 2:22).

  • Hide God’s Word in Your Heart:Memorizing and meditating on Scripture allows one to resist temptation through divine truth (Psalm 119:11).

  • Make No Provision for the Flesh: Proactively removing opportunities for sin (e.g., avoiding, managing technology, or changing habits) (Romans 13:14).

  • Renew Your Mind: Focusing thoughts on what is true, honorable, and pure to replace sinful inclinations (Romans 12:2, Philippians 4:8).

  • Accountability and Community:Surrounding yourself with other believers to encourage holiness and provide correction (Hebrews 10:24-25).

  • Prayer and Dependence on God:Asking for God's help to escape temptation and, through prayer, acknowledging reliance on Him (Matthew 6:13, 1 Corinthians 10:13). 
    The ultimate goal is to allow God's grace to transform the heart, making one want to please Him, rather than relying solely on willpower.

One doesn't discover new lands without consenting to lose sight of the shore for a very long time.

My main problem is overeating-that’s a euphemism for gluttony.

Recovery means going to any lengths to stay abstinent. It means being willing to give up, for today, any or all of the comfortable and familiar old ways that may interfere with abstinence, including cooking, restaurants, friends, meals for my family, flag and country. I find it isn’t necessary to give up these things, but I had to be willing; willingness is the key. Without abstinence I have nothing except a killing, progressive disease.
For today: I am willing to put abstinence first. That means talking to anyone who is able to help me, asking questions even though they may make me appear foolish, making phone calls even though I may bother someone.
