What You Feed Grows; What You Starve Dies

A War Already Decided

Before the farming, there is a fact that must be established, because without it everything else becomes a self-improvement project.

Paul has just said: "And they that are Christ's have crucified the flesh with the affections and lusts" (Galatians 5:24). Past tense. Already done.

He says it again in Romans: "For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live" (Romans 8:13). Notice who does the mortifying — you, through the Spirit. Not you alone, and not the Spirit alone.

So the position is this. The old nature was dealt with at the cross. Its desires remain as a voice, and a voice is fed or starved.

The Divine Nature — the life of God in you — is what grows when fed. Renewing of the Mind — the reshaping of your thinking — is how the feeding works. The Life of the Spirit — walking by His leading — is the outcome.

Consider a man who moves into a house with a garden full of weeds. He is not asked to invent a garden. He is asked to decide, week by week, which plants get water.

Two Appetites, One Mouth

The image of eating is the clearest one Scripture uses, and it is not accidental.

Paul says, "For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit. For to be carnally minded is death; but to be spiritually minded is life and peace" (Romans 8:5–6).

Mind there is a verb as much as a noun — the things you set your attention on. Which is why the appetite is not defeated by a single dramatic decision but by a thousand small servings.

Set the two lives side by side. One believer fights a habit by willpower alone, loses, repents, and repeats — and each round makes him more convinced he is hopeless. Another feeds the Word, feeds prayer, feeds fellowship, and quietly starves the other appetite until it loses its voice. The first is fighting a plant with a knife. The second is cutting off its water.

Starving Is Not Passive

Here is where the metaphor must be handled honestly, because "starve it" can sound like doing nothing, and doing nothing is not the instruction.

A weed starved still puts out roots. It will look dead, and then revive at the first rain. Have you been calling something dead that was only dry? Starving something means removing what feeds it — deliberately, repeatedly, and usually at the level of ordinary habit.

That means identifying the thing that waters it. Rarely is it only the sin itself. It is usually a routine: the hour, the company, the screen, the loneliness, the unpaid bill. Paul's word in Colossians is "mortify" (Colossians 3:5) — put to death — and it is an active verb aimed at the roots.

What Actually Feeds the New Nature

The Word, plainly. Not only reading but taking it in: hearing, meditating, speaking, obeying.

And alongside it, the ordinary means Paul lists in the same letter: "Walk in the Spirit, and ye shall not fulfil the lust of the flesh" (Galatians 5:16). Walking is a daily, unremarkable activity. It is not a crisis experience; it is a direction.

Peter's version puts the food and the growth together: "As newborn babes, desire the sincere milk of the word, that ye may grow thereby" (1 Peter 2:2). Desire and diet. Appetite and intake. Growth is the result of both, and neither is passive.

The Appetite Follows the Diet

Something worth knowing about appetites: they are trainable.

A man who eats sugar for a month finds vegetables tasteless and then finds, after two weeks of vegetables, that sugar is overpowering. Appetite is not a fixed fact about a person. It is a report on what he has been eating.

Which means a believer who says "I just do not have a hunger for the Word" is describing a state that can be changed, not a constitution that must be accepted. The hunger comes back, usually slowly, from the discipline of eating before the desire arrives.

The Fruit Test

Paul gives the outcome in a list rather than an argument: "But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance" (Galatians 5:22–23).

A tree is known by fruit, and fruit is what a tree produces when it is fed. Not strained for. Produced.

That is the mercy at the end of this teaching. You are not asked to manufacture love, joy, and peace by effort. You are asked to keep the tree in the sun and the soil, and let the fruit be the outcome of provision.

The Honest Boundary

One thing to say plainly, because this teaching can be misused.

Some struggles are not appetites but wounds — patterns formed by trauma, addiction with a physiological grip, depression that is not a discipline problem. Telling a wounded person to "starve it" can deepen shame without changing anything.

Paul's own instruction sits inside a life of community, counsel, and time. If the appetite you are fighting has a medical or traumatic root, starving it is not the whole answer, and getting help is not a lack of faith.

What This Means for You

1. Name what you are feeding. What did you give your attention to most this week? That is the answer, and it is more honest than your intentions.

2. Cut one supply line. Not the sin itself — the routine that keeps it alive. Remove the water and watch what happens.

3. Add one daily serving of the Word. Small and fixed beats large and occasional. The appetite will follow.

4. Expect the hunger to lag. Eat before you feel like it. That is what discipline is for.

5. Let Faith and Wisdom work together here. Faith says the new nature is real and will grow. Wisdom says growth needs a plan — a fixed time, a person who asks you honest questions, and the humility to get help where the root is deeper than habit.

Putting It to Work This Week

• Read Galatians 5:16–25 three times this week.
• Write down the supply line of one appetite you want starved.
• Feed the new nature once a day at a time you can actually keep.
• Read Romans 8:5–13, and note what Paul says the mind does.
