Structure of 1 John
Author & Background
Author: The Apostle John, son of Zebedee, the "beloved disciple." Also wrote the Gospel of John, 2-3 John, and Revelation.
Date: ~85-95 AD, likely from Ephesus.
Audience: Believers in Asia Minor (modern-day Turkey), possibly a house-church network.
Occasion: False teachers (proto-Gnostic) had left the fellowship, denying that Jesus had come in the flesh and claiming special spiritual knowledge. John writes to reassure true believers and expose the false.
John's Four Purposes
- Joy (1:4) — "that your joy may be full" — the right attitude
- Holiness (2:1) — "that you sin not" — the right action
- Assurance (5:13) — "that you may know you have eternal life" — the right assurance
- Discernment (2:26) — "concerning those who try to deceive you" — the right alarm
The Three Tests of Genuine Faith
John weaves three "tests" throughout the letter. A true child of God will exhibit all three:
1. The Moral Test — Righteousness
"He who says he abides in Him ought himself also to walk just as He walked" (2:6). Genuine faith produces obedience.
2. The Love Test — Love for the Brethren
"He who loves his brother abides in the light" (2:10). Genuine faith produces love for God's people.
3. The Doctrinal Test — Confession of Christ
"Every spirit that confesses that Jesus Christ has come in the flesh is of God" (4:2). Genuine faith holds to true doctrine about Christ.
