1. Observe

   According to verse 4, what is the victory that has overcome the world?

   • Obedience to the commandments
   • Love for one another
   • Our faith
   • Suffering endured patiently

2. Observe

   What three witnesses does John list in verses 7-8, and what do they agree on?

   • The law, the prophets, and the apostles — that Jesus is Messiah
   • The Spirit, the water, and the blood — and the three agree as one
   • The Father, the Son, and the Spirit — that God exists in Trinity
   • Scripture, tradition, and reason — that eternal life is possible

3. Interpret

   What does John mean by stating his purpose as "that you may know that you have eternal life" (v. 13)? How is such assurance possible without arrogance?

   • It means Christians can be certain only if they have had an emotional conversion experience
   • Assurance is not possible — John only means that readers should hope they have eternal life
   • John grounds assurance in objective facts — believing in the name of the Son of God, having the Spirit as a witness, and possessing the Son in whom life resides — so confidence rests not on self-assessment but on what God has testified and given; this is faith in a reliable promise, not pride in personal performance
   • Eternal life can only be known at death when God renders a final verdict

4. Interpret

   What does "a sin leading to death" (v. 16) refer to, and how does the surrounding context shape its meaning?

   • Any sin that causes physical illness or early death
   • Sins committed on the Sabbath
   • Most likely a definitive, willful rejection of Jesus Christ — the kind of apostasy that characterizes the false teachers who have denied the Son and departed; John's contrast is between brothers who stumble and those who have placed themselves outside the life that is only in the Son
   • Accidental sins that have not been confessed within a set time

5. Apply

   John closes with "keep yourselves from idols" (v. 21). Given his whole letter, what kinds of idols are most likely to compete with the true God in the life of a modern believer?

   • Only carved statues and images in pagan temples
   • Political ideologies and voting preferences
   • False pictures of God shaped by false teaching — a Jesus who did not really come in the flesh, a God whose love is earned by performance, or any ultimate love (comfort, status, approval) that displaces the true Son who alone gives life
   • Secular music and entertainment

6. Apply

   "He who has the Son has the life" (v. 12). How does this binary — having the Son or not having the Son — affect the way you share the gospel with people you love?

   • It suggests the gospel is too exclusive to share with non-Christians
   • It means conversion is purely God's work and humans play no role in it
   • Knowing that eternal life is inseparable from a relationship with the Son — and that those without him do not have it — gives urgency and compassion to sharing the gospel; the stakes are real and the gift is freely offered
   • It is relevant only for professional missionaries
