The New Testament uses the Greek word enkrateia for self-control — a compound of en (within) and kratos (power, dominion). Self-control in Scripture is not white-knuckled resistance. It's a power that operates from the inside, a dominion over the interior life. Galatians 5 lists it as a fruit of the Spirit, which means it's not primarily a human achievement — it's a Spirit-produced quality that grows in a life yielded to God.
First Corinthians 10:13 is the recovery verse that gets quoted often, but its full weight is frequently missed: "God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it." The phrase "way to escape" is ekbasin — a way out, a passage through. This isn't a guarantee that you won't face serious temptation. It's a guarantee that the temptation is never sealed shut. There is always a door. The work is staying close enough to God to see it.
The theology of identity is also crucial here. Addiction has a way of becoming the central fact of a person's story — their primary name. Paul writes in 1 Corinthians 6:11 about those who had been drunkards, and uses the past tense: "such were some of you." Were. The person you are in Christ is not the same person you were in that pattern. That's not denial — it's the declaration of what the gospel does to identity.
