Day 24 — Purity

“For it is God’s will that you should be holy: You must abstain from sexual immorality; each of you must know how to control his own body in holiness and honor… For God has not called us to impurity, but to holiness.”

— 1 Thessalonians 4:3–4, 7 (BSB)

People often ask, “What is God’s will for my life?” and imagine it’s a mystery only revealed after years of prayer. Paul says, Here’s one part of it, plainly: “it is God’s will that you should be holy.”

Being pure isn’t about being naïve, or pretending you don’t have feelings. As you grow up, new and strong desires arrive. That’s not shameful. God designed your body and your sexuality, and He called His creation “very good.” Desire isn’t the enemy. But like fire, it’s good in the right place and destructive in the wrong one. God’s design is for sex to belong within marriage between a husband and wife, and He asks us to honour that with our bodies, our eyes and our minds — now, not just later.

Paul says each of us “must know how to control his own body in holiness and honor.” Know how suggests something learned. Nobody is born with self-control. It’s practised, the way you practise an instrument or a sport.

Let’s be honest about the world you live in. Sexual content is everywhere, and much of it can reach a phone in seconds. Pornography is one of the biggest battles for teenagers everywhere, and it trains the mind to see people as objects rather than as people made in God’s image. If that’s already a struggle for you, you are not a freak, and you are not beyond help. Shame tells you to hide. Jesus tells you to come into the light.

Some practical wisdom:

Decide ahead of time. The middle of a moment is the worst place to make a decision. Choose your boundaries now — with your phone, with what you watch, with how far is too far in a relationship.

Use the guardrails. Keep your phone out of your bedroom at night. Talk with a parent about filters and settings. This isn’t about being weak. Smart people put barriers where they know they’re vulnerable.

Guard your heart, not just your actions. “Guard your heart with all diligence, for from it flow springs of life” (Proverbs 4:23).

Talk to someone. A parent, or a trusted adult at church, has heard it all before. Questions about your body, relationships or something you saw belong with them, not with the internet.

And hear this clearly: if anyone pressures you, sends you things you don’t want, asks you for pictures, or touches you in a way that’s wrong, it is not your fault. Tell a trusted adult right away, even if you’ve been told to keep it secret.

If you’ve already gone further than you wish you had, purity is not lost forever. David, after his worst failure, prayed, “Create in me a clean heart, O God, and renew a right spirit within me” (Psalm 51:10). God still answers that prayer. Purity is not a scoreboard. It’s a direction you walk, with Him.

Think about it: Where are you most vulnerable — a time of day, a place, an app? What guardrail would help?

Try this: Make one practical change today, such as charging your phone outside your bedroom tonight. If there’s something you need to talk about, choose the adult you’ll talk to this week.

Go deeper: Purity of Heart by William Booth — the founder of the Salvation Army reminds us that purity is bigger than one area of life: being “right and honest and true inside and out,” a heart with nothing else mixed in. Start with chapter 1, “Purity: What It Is.”

Holy God, thank You for making me, body and mind, and calling it good. I want to be holy because You are holy. Give me self-control, wisdom with my phone and my eyes, and courage to bring my struggles into the light. Where I have failed, wash me and create in me a clean heart. In Jesus’ name, Amen.
