Put It to Death, Do Not Manage It

There is a difference between a man fighting his sin and a man feeding it, and the terrifying thing is how similar they look from the outside. Both of them talk about the struggle. Both of them go to church. Both of them mean it when they say they want to change. But one of them is killing the thing and the other one is keeping it alive, and only one of them is going to get free.

Paul does not use soft language for this. "For if you are living according to the flesh, you must die; but if by the Spirit you are putting to death the deeds of the body, you will live" (Romans 8:13). Putting to death. And elsewhere he says it again, just as hard: "Therefore consider the members of your earthly body as dead to immorality, impurity, passion, evil desire, and greed, which amounts to idolatry" (Colossians 3:5). Put to death. Consider it dead. The old writers had a word for this, mortification, and they meant it in the literal sense. You are killing something.

Life support is not war

Here is the thing most men do instead, and it feels like fighting, which is exactly why it is so dangerous.

They keep the sin on life support. They do not want to kill it. Not really. They want it manageable. Small enough that it does not blow up their life, quiet enough that nobody finds out, contained to a room they think they can keep it in. And they call the containment a struggle, and they feel virtuous about the containment, because containing it feels like the same thing as fighting it.

It is not. A man keeping his sin small is not at war with it. He is its caretaker. He has decided the thing gets to live, just on a leash, and he is going to spend the rest of his life managing the leash, and the leash is going to snap on a night he is tired, because leashes always do. You do not put a predator on a diet. You do not negotiate a smaller amount of the thing that wants you dead. You kill it, or it waits.

What killing it actually costs

Mortification is not a mood. It is not feeling bad about the sin. Men feel terrible about their sin all the time and never kill it, because guilt is not the same as death, and the flesh is perfectly happy to let you feel guilty forever as long as you never actually put a knife in it.

Killing it looks like a Tuesday. It looks like a man cutting the supply lines, the specific things that feed the specific sin, and cutting them at the root, not trimming them. It looks like confessing it to a real person in daylight so it cannot keep living in the dark where it feeds. It looks like refusing to be alone with it in the hours it hunts. And it looks like doing all of that by the Spirit and not by raw willpower, because Paul is specific, by the Spirit you are putting to death the deeds of the body, and the man trying to kill his sin on his own strength is bringing his fists to a fight the flesh has already war-gamed a thousand times.

You cannot manage this into submission. You have tried, for years, and the years are the evidence. The thing is still alive because you have been feeding it while telling yourself you were fighting it. Stop keeping it small. Stop feeling bad instead of acting. Put it to death, by the Spirit, at the supply line, in the daylight, today, and keep putting it to death tomorrow, because a dead thing that you stop guarding has a way of getting back up, and this is a war that does not end. But there is only one of the two roads that leads anywhere but the grave, and Paul already told you which one. Put it to death, and you will live.
