Chapter 3: Biblical Principles on Purity and Self-Control

“Blessed are the pure in heart, for they will see God.”
— Matthew 5:8

Purity begins in the heart—self-control grows by the Spirit.

Parable: The Clear Spring

There was a village built beside a spring that fed every home. The water was once so clear that children could see smooth stones at the bottom and fish flickering like silver in the sunlight.

Upstream, the spring was protected by a small fence and a simple sign: “Guard the source.” For years, the villagers respected it. They knew that what happened at the spring would shape everything downstream.

But one season, people grew careless. A little trash here. A little mud there. “It’s just a small thing,” they said. The spring kept flowing, so no one felt urgency.

Slowly the water changed. Not all at once—just enough that the taste became dull and the stones disappeared beneath cloudiness. Families blamed the buckets, the pipes, the weather—anything except what they were allowing near the source.

One morning, an old gardener walked upstream with a lantern and a shovel. He didn’t accuse anyone. He simply said, “If you want clean water, you must protect the spring. The river can’t stay pure if the source is treated like a trash bin.”

The villagers began clearing what had been thrown in. It was work. It was humbling. But as the spring became clean again, the water downstream began to change. What felt impossible in the homes became possible at the source.

Moral:
A spring stays clear when it is guarded upstream. Purity is protected at the source—what you allow into your mind and heart will flow into your life.

Introduction: The Call to Purity

God calls us to live lives of purity and self-control, not to limit our joy but to protect and guide us toward His best for our lives. This chapter explores what it means to pursue purity, how self-control is developed as a fruit of the Spirit, and how these principles can shape our decisions, particularly regarding our bodies and sexuality.

1. What Is Purity?

Purity is more than just avoiding sin—it’s a condition of the heart that seeks to honor God in every thought, word, and action.

“Create in me a pure heart, O God, and renew a steadfast spirit within me.”
— Psalm 51:10

Do This Now

Take a moment to pray and ask God to show you areas in your life where you need greater purity. Write down one step you can take today to align your thoughts and actions with His will.

  • What does it mean for your heart to be pure before God?
  • Are there areas where you struggle with impure thoughts or actions?
  • How can prayer and Scripture help cleanse your heart?

2. Why Self-Control Matters

Self-control is essential for living a life that honors God. Without it, our desires can lead us away from His purpose for us.

“No temptation has overtaken you except what is common to mankind. And God is faithful; He will not let you be tempted beyond what you can bear.”
— 1 Corinthians 10:13

Do This Now

Write down a situation where you’ve struggled with self-control. Reflect on how you can prepare for similar situations in the future using prayer, Scripture, or accountability.

Questions to Reflect On

  • How does self-control impact your relationship with God?
  • What areas of your life require greater discipline?
  • How can you rely on God’s strength to resist temptation?
  • Who can help hold you accountable as you grow in self-control?

3. Guarding Your Mind and Heart

Your mind is a battlefield where spiritual growth and purity are won or lost. Guarding your thoughts is critical to maintaining purity.

“Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure… think about such things.”
— Philippians 4:8
“You are what you think. Your thoughts shape your life.”
— Proverbs 23:7 (paraphrased)

Do This Now

List three things you frequently allow into your mind (TV shows, music, social media, etc.). Evaluate whether they encourage purity or lead you toward temptation.

Questions to Reflect On

  • What thoughts do you struggle to control?
  • How does guarding your mind impact your ability to stay pure?
  • What habits or influences could you change to protect your heart?
  • How can Scripture help transform your thoughts?

4. Practical Strategies for Purity

God provides tools and resources to help us pursue purity in a world full of temptations.

“As iron sharpens iron, so one person sharpens another.”
— Proverbs 27:17

Do This Now

Choose one practical strategy (e.g., setting boundaries, finding an accountability partner) and commit to implementing it this week.

Questions to Reflect On

  • What triggers temptations in your life?
  • Who can you trust to support you in staying accountable?
  • How can daily prayer and Bible study strengthen your pursuit of purity?
  • What boundaries can you set to avoid tempting situations?

5. The Reward of Purity

Living a pure life brings spiritual rewards and a deeper relationship with God.

“Great peace have those who love Your law, and nothing can make them stumble.”
— Psalm 119:165

Do This Now

Write a prayer thanking God for the blessings that come with purity. Reflect on how these blessings can motivate you to stay on the path He has set for you.

Questions to Reflect On

  • How has pursuing purity brought you closer to God?
  • What peace or joy have you experienced through honoring Him with your life?
  • How can the promise of “seeing God” encourage you in moments of struggle?
  • What steps will you take today to pursue these rewards?
