Gluttony, fasting, and self-control — Biblical Eating

The two failures

Scripture critiques two opposite mistakes around food. Both are forms of treating the body as a god:

Gluttony says the answer to life is more. More food, more pleasure, more comfort. Proverbs 23:20-21 yokes the glutton with the drunkard. Philippians 3:19 names the worst-case as those whose "god is their belly." Deuteronomy 21:20 considers persistent gluttony a marker of rebellion.

Anorexic asceticism says the answer is denial. Paul calls out a strain of false teaching that "forbids marriage and requires abstinence from foods that God created" (1 Tim 4:3). Colossians 2:20-23 dismisses harsh self-denial as having "an appearance of wisdom" but "no value in stopping the indulgence of the flesh."

The healthy middle: food is a gift, the body is entrusted, appetite is to be governed but not despised.

Self-control as a fruit of the Spirit

Galatians 5:22-23 lists self-control as the ninth fruit of the Spirit. It is the only fruit that explicitly governs the relationship between will and appetite. Self-control is not white-knuckle willpower — it is the Spirit-given capacity to do what you actually want to do, against the pull of short-term wants.

Practical signs that self-control is growing:

You can pass on a snack without internal drama
You can stop one bite before you "have to"
You can fast a meal without rage at coworkers
You can enjoy a feast without feeling guilty afterward
Your relationship to food is quiet — neither obsessive nor performatively casual

Fasting in scripture

Fasting is the deliberate, time-bounded abstinence from food for spiritual purpose. Scripture treats it as expected (not commanded) — Matthew 6:16 says when you fast, not if.

The major patterns:

Penitential fasting — Joel 2:12-13, Jonah 3:5-9, Daniel 9. Fasting as bodily confession.
Petitionary fasting — 2 Sam 12:16-23 (David fasts for his son), Esther 4:16, Acts 13:2-3, 14:23. Fasting alongside intense prayer.
Preparational fasting — Moses (Ex 34:28), Elijah (1 Kings 19:8), Jesus (Matt 4:1-2). Before a major spiritual undertaking.
Mournful fasting — David at Saul's death (2 Sam 1:12), the disciples after Jesus' death (Matt 9:14-15).
Communal fasting — the Day of Atonement (Lev 16:29-31; 23:27-32); declared fasts in times of national crisis.

Fasting today

Jesus' teaching (Matt 6:16-18) governs the practice. Three principles:

Privacy. Don't perform it. The reward of God-seen fasting is God-seen. The reward of advertised fasting is the audience.
Normalcy. "Anoint your head, wash your face" — don't look the part. Carry on your day as usual.
Purpose. Fasting is for something — prayer, dependence, repentance, focus. Fasting for weight loss alone is dieting, not the spiritual practice.

A starter pattern that has worked for many Christians for two thousand years:

One meal — skip lunch on Wednesday or Friday. Spend the hour in prayer or scripture.
One day — sundown to sundown, water only. Best paired with a specific intention (a decision, a person, a season).
Three days — biblical pattern (Esther, Jonah, Paul in Damascus). Should not be undertaken without checking with a doctor for anyone with relevant health conditions.
Longer — extended fasts above three days have a serious tradition but require physical and spiritual preparation. Don't lead with it.

A word for those with eating disorders

If you have or have had anorexia, bulimia, binge eating disorder, or obsessive disordered eating, the spiritual practice of fasting is not the place to begin. Scripture takes the body seriously enough to honor when an instrument is wounded. Talk to a doctor and a mature pastor before fasting. There are dozens of other formative practices — silence, solitude, scripture meditation, almsgiving, sabbath — that will form the soul without putting a damaged tool back on the workbench too soon.

The two questions to ask weekly

In the last seven days, did food rule me?
In the last seven days, did I rule food in a way that excluded gratitude and joy?
