1 John: Truth, Love, and Assurance

Background

Author

The letter doesn't name its author, but early church writers, beginning with Irenaeus in the late second century, attribute it to the apostle John. Its vocabulary and themes closely match the Gospel of John. The author writes as an eyewitness (1:1–3) with pastoral authority over his 'little children.'

Date

Most likely between AD 85 and 95, probably from Ephesus, where early tradition places John in his later years.

Setting

A group had left the congregation (2:19) and was teaching that Jesus Christ had not truly come in the flesh (4:2–3). This resembles early forms of the movements later called Docetism and Gnosticism, which treated the physical world as unimportant or evil. The believers who remained were unsettled and unsure where they stood.

Purpose

John states his purposes directly: that their joy may be full (1:4), that they may not sin (2:1), and that they may know they have eternal life (5:13).

Structure of the book

• 1:1–4 Prologue: the Word of life seen and touched
• 1:5–2:27 Walking in the light; tests of true faith
• 2:28–4:6 Children of God; testing the spirits
• 4:7–5:12 God is love; the testimony about the Son
• 5:13–21 Confidence and assurance

This course runs on the same lesson machinery as Nehemiah; its passage text is still being prepared from the public-domain dataset, so the Read step shows the passage reference until the text is bundled (Milestone 4 completes these two courses).
