"Mewing" is a facial-posture exercise (tongue pressed against the roof of the mouth) believed by its advocates to reshape the jawline over time. Mainstream orthodontics is skeptical of the claimed effects. Gen-Z and male-aesthetics culture have embraced it as part of a broader "looksmaxxing" project — disciplined optimization of personal appearance. The Christian observation: bodily discipline is not forbidden but is sharply limited in eternal weight. "For bodily exercise profiteth little: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come" (1 Timothy 4:8). Effort spent reshaping the jaw is effort not spent reshaping the soul. "Favour is deceitful, and beauty is vain: but a woman that feareth the LORD, she shall be praised" (Proverbs 31:30). Same for men.
Tongue-posture facial-aesthetics practice (Dr. John Mew, 1970s) re-popularized by Gen-Z looksmaxxing culture.
MEWING, v. Tongue-posture exercise (tongue pressed to roof of mouth, lips together, teeth lightly together) claimed by British orthodontist John Mew (and son Mike Mew) to gradually reshape the jawline. Adopted enthusiastically in twenty-first-century male-aesthetics and Gen-Z TikTok communities as a no-cost looksmaxxing practice. Mainstream orthodontic consensus is skeptical of the long-term aesthetic claims; the practice is harmless in itself.
1 Corinthians 6:19-20 — "What? know ye not that your body is the temple of the Holy Ghost which is in you... ye are bought with a price: therefore glorify God in your body."
1 Samuel 16:7 — "But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature... for the LORD looketh on the heart."
1 Peter 3:3-4 — "Whose adorning let it not be that outward adorning... but let it be the hidden man of the heart."
Body stewardship is good; building identity on jawline angle is idolatry by another name.
Mewing itself is a minor practice; the deeper category is what it serves. Looksmaxxing culture has trained young men to identify with their facial geometry — jaw angle, chin projection, hunter eyes — and to organize daily practice around it. That is not body stewardship; that is identity-construction on the wrong foundation.
1 Sam 16:7 names the substitution directly: the LORD looks on the heart. The young man who reorders his daily practice around jaw symmetry has accepted the world's economy — appearance as identity — while declining the one his Lord uses. The cure is not no body care; it is reordered priority. Care for the body as temple (1 Cor 6:19-20). Build the inner man as ornament (1 Pet 3:4). Mew if you want; just know what foundation you are building on.
