Overcoming sin requires both practical discipline and the Holy Spirit's work. Find accountability partners, avoid tempting situations, and take concrete steps to resist. But human effort alone won't stick; real change comes when the Spirit transforms your heart so old temptations repel you.
The key to overcoming sin isn't necessarily found in fighting old desires. You should be accountable to other believers. You should avoid opportunities and tempting situations. You should do all things practical that you can in order to stand against that which tempts you. But after all of that has been applied, you have to recognize that it's not by power nor by might, but By my Spirit, says the Lord. It's one thing to fight old desires. It's another thing to have those desires changed. You see, there's a work that the Holy Spirit does that's so deep that as the Holy Spirit works in you, eventually what once tempted you will soon repel you.
