1 John
Introduction
First John strengthens believers’ assurance of eternal life and calls them to remain faithful to Jesus Christ. It responds to deceptive teaching by emphasizing the reality of Christ’s coming in the flesh, obedience to God, and love for fellow believers.
The letter repeatedly connects truth, righteousness, and love. God is light and God is love; those who know Him should reflect His character. Assurance rests in His Son and is accompanied by a life of faith, confession, obedience, and practical love.

Fellowship with God and Walking in the Light
Read chapter 1 (AMP)John announces the life revealed in Jesus Christ, whom the witnesses heard, saw, and touched. His purpose is to bring readers into fellowship with the Father, the Son, and fellow believers. (1 John 1:1–4).
God is light, and fellowship with Him cannot be reconciled with walking in darkness. Those who walk in the light share fellowship and are cleansed by Jesus’ blood. (1 John 1:5–7).
Claiming to be without sin is self-deception. When believers confess their sins, God faithfully forgives and cleanses them; denying sin contradicts His word. (1 John 1:8–10).
Chapter 2
Obedience, Love, and Remaining in Christ
Read chapter 2 (AMP)John writes so believers will not sin, yet points those who do sin to Jesus Christ, their Advocate and atoning sacrifice. Knowing Him is demonstrated by obedience and walking as He walked. (1 John 2:1–6).
Love for fellow believers belongs to walking in the light. John encourages believers at different stages of growth and warns against worldly desires and pride that pass away. (1 John 2:7–17).
Deceivers deny the Father and the Son. Believers must hold to the message they received, remain in Christ, and live righteously as they await His appearing. (1 John 2:18–29).
Chapter 3
Children of God and Love in Action
Read chapter 3 (AMP)God’s love gives believers the privilege of being His children. The hope of becoming like Christ at His appearing calls them to purity, while a life characterized by sin conflicts with their new birth. (1 John 3:1–10).
Unlike Cain, believers should love rather than hate. Jesus’ self-giving love is their pattern, and concern for a brother or sister in need must become practical action. (1 John 3:11–18).
God is greater than a condemning heart. Confidence before Him accompanies faith in Jesus Christ, obedience, and love for one another; His Spirit confirms His abiding presence. (1 John 3:19–24).
Chapter 4
Testing Teaching and Living in God’s Love
Read chapter 4 (AMP)Believers must test spiritual claims instead of accepting every teacher. Confessing Jesus Christ as having come in the flesh marks the truth, and God’s presence in His people is greater than the world’s opposition. (1 John 4:1–6).
God’s love was revealed by sending His Son to give us life and deal with our sins. Because He first loved us, believers must love one another and remain in His love. (1 John 4:7–16).
Love brings confidence concerning judgment and drives out fear of punishment. A claim to love God is contradicted by hatred toward a fellow believer. (1 John 4:17–21).
Chapter 5
Faith in the Son and Assurance of Eternal Life
Read chapter 5 (AMP)Those who believe Jesus is the Christ are born of God. Love for God includes obedience, and faith in His Son overcomes the world. (1 John 5:1–5).
God bears witness to His Son through the Spirit, the water, and the blood. Eternal life is God’s gift in Jesus Christ: having the Son means having life. (1 John 5:6–12).
John writes so believers may know they have eternal life. He encourages prayer according to God’s will and intercession for others, addresses sin leading to death, and closes by urging believers to guard themselves from idols. (1 John 5:13–21).
