How Not to Sin

Introduction to 1 John 2:1-2

My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ, the righteous. He is the propitiation for our sins and not for ours only, but also for the sins of the whole world.

1 John 2:1-2

This letter from John the Apostle helps us understand what it means to be a Christian. It assures us of our salvation and encourages us to believe what is true about Jesus Christ—a matter of life and death.

John writes for our complete joy, fellowship with other Christians, and fellowship with God Himself. God is light, and in Him is no darkness. If we claim to be Christians yet walk in darkness, continuing in sin with no difference from unbelievers, we deceive ourselves. What we do does not make us Christians, but it demonstrates whether we are.

Christians walk with God and others, but God does not fellowship with sin. Only those cleansed by Jesus' blood have relationship with Him.

Imagine claiming a relationship with a Hollywood star whose lifestyle opposes yours—no one would believe it. Similarly, if our lives contradict God's ways, we cannot truly claim relationship with Him.

The difference between sinners with God and without is confession. Walking in the light means exposing sin openly. Light reveals, so Christians confess sins—not just to God, but to each other. David said his unconfessed sin caused physical pain.

Why confess embarrassing sins like immorality, drunkenness, disobedience, lying, anger, or hatred? Because Jesus' blood cleanses us. God is faithful and just to forgive and purify us. With Jesus crucified for us, who can condemn? Even with ongoing sin, we remain justified.

The Goal: Not to Sin

John clarifies he is not demanding sinless perfection. Everyone sins, but he writes so we may not sin. The goal is joy, fellowship, and turning from sin—not excusing it because we are forgiven.

If we sin, we have an advocate with the Father: Jesus Christ, the righteous.

Jesus: Our Advocate

The Greek word for advocate is parakletos—one called alongside to help, a comforter or lawyer. Jesus defends us before the Father: "Case dismissed because of Me." The Son speaks positively about you in the Trinity, having accomplished your salvation as the Father planned. They rejoice over you.

How encouraging to know Jesus prayed for you in John 17, wears your name on His breastplate as High Priest, and lives to intercede for you now.

Jesus: Our Propitiation

Jesus is the propitiation (hilasmos) for our sins—appeasing God's wrath, removing it entirely, restoring joyful relationship.

Before Christ, we live under God's active wrath. He hates sinners, delaying judgment only by His pleasure. Animal sacrifices temporarily propitiated, but Jesus does it totally and finally. Justice satisfied, God can never punish you again—your wrath is gone forever.

With wrath removed, only God's omnibenevolent love remains. He is a good Father, pouring out perfect holy love on His children.

For John's Jewish audience, this was mind-blowing: no more repeated sacrifices. But it extends beyond Jews—"not for ours only, but also for the sins of the whole world." Grasp your propitiation, then share it with every tribe and nation.

How Not to Sin Leads to Joy

John starts with "my little children, I am writing these things so that you may not sin." Jesus removed wrath due to sin—yet we still sin. Does forgiveness mean we can sin freely? No.

True Christians—those in light, confessing sin—find joy in repentance. Sin hinders fellowship with God and believers. Unconfessed sin made the speaker prefer unbelievers' company, chasing empty pleasures: dating, drinking, drugs. Now he sees their futility and warns youth against it.

Jesus' forgiveness motivates holiness, not license. Joy comes from soul-satisfying fellowship with God, greater than sin's passing pleasures.

Moses left Pharaoh's riches for wilderness reproach with God's people, esteeming Christ's reproaches greater than Egypt's treasures. Sin's pleasures are fleeting; gospel joy endures.

Jesus promises in John 15 to make your joy complete—His own unshakeable joy amid suffering. John writes for this total joy.

Application

Do you want complete joy, or sin's temporary pleasures that condemn eternally? Put faith in Christ, your advocate and propitiation. Trust Him to remove sin's barrier to God.

If saved, recognize sin robs joy. Even when you sin, Jesus forgives. Live in newness, walking in light. Don't hide sin—confess and rejoice in cleansing.
