Message Notes
The notes cover the introduction to 1 John, background on the author (John the Apostle), key details about the book, and an exposition of 1 John 1:1–4.
Transition & Series Context
Preacher finished 2 Peter; now moving to another non-Pauline epistle: 1 John.
Plans to work through 1 John (no guarantee to continue with other epistles afterward).
Today: Author background, introductory comments on the book, and exposition of only 1 John 1:1–4.
Who Was John the Apostle? (Author Background)
One of the 12 disciples; generally considered the youngest (likely 10 years younger than Jesus).
At Jesus’ ministry start (~age 30), John was probably ~20 or younger (possibly late teens: 18–19).
Contrast: Peter (one of the oldest disciples) ~10 years older than Jesus → ~20-year age gap between Peter and John.
Family:
Son of Zebedee (fisherman) and Salome (likely pronunciation).
Younger brother of James (another disciple).
Lived in Bethsaida and/or Capernaum (north shore of Sea of Galilee).
Likely first cousin of Jesus (strong evidence, though not 100% certain):
Women at the crucifixion (Matthew 27:55–56; Mark 15:40; John 19:25) list overlaps → Salome (mother of James/John) identified as sister of Mary (Jesus’ mother).
Explains family interactions, e.g., Zebedee’s lack of objection when sons left family business (Mark 1:19–20); Salome’s bold request for sons’ thrones (Matthew 20:20–21); Jesus entrusting Mary to John (John 19:26–27).
Family business: Successful fishing operation (“Zebedee and Sons”) with hired servants → not poor; possibly two homes (Galilee + Jerusalem?); family financially supported Jesus’ ministry.
Known to high priest (John 18:15–16) → reinforces social/connections status.
Inner circle: One of three closest to Jesus (with James and Peter).
Nicknamed “Sons of Thunder” (Mark 3:17) — possibly fiery temperament (e.g., wanting fire on Samaritans, Luke 9:51–56; trying to stop non-follower exorcist, Luke 9:49–50).
Post-resurrection/ascension life (from Scripture + early church history):
Stayed in Jerusalem early on (often with Peter in Acts).
Likely remained until after 70 AD (temple destruction).
Moved to Ephesus (church Paul founded); served as elder/teacher.
Exiled to Patmos → received Revelation.
Returned to Ephesus; spent later years there.
Writings (late in life, ~80s AD): Gospel of John, 1–3 John, possibly Revelation (debated timing).
Wrote 1 John in his 80s (~90–95 AD).
Character transformation: Early “rough edges” (fiery, impulsive) → later emphasis on love (e.g., “God is love”; 46 mentions of love in 1 John; John 3:16).
Introduction to the Book of 1 John
Author: John the Apostle (anonymous in text, but undisputed by early church; style/tone matches Gospel/Revelation).
Date: ~90–95 AD (late 1st century; John in Ephesus, elderly).
Theme / Purpose:
Focus on fundamentals of the faith: Sound faith, obedience, love → evidence of true conversion.
Assurance: “I write these things… that you may know that you have eternal life” (1 John 5:13).
Combats early heresy (e.g., Gnosticism / proto-Gnostic views questioning Jesus’ humanity; cf. Docetism-like ideas that Christ only “appeared” human).
John stresses: Jesus is fully God (eternal Word) + fully man (heard, seen, touched).
Style: Repetition / cyclical — returns to themes (faith, obedience, love, sin) with added depth → reinforces importance, aids memory.
16 Evidences of True Conversion (proofs, not causes; show changed life):
Spiritual fellowship with God/others.
Sensitivity to sin.
Forgiveness/cleansing/restoration after confession.
Keeping His commandments.
Doing God’s will.
Life characterized by righteousness.
Anticipating Christ’s return.
No longer habitual sin.
Love for brethren.
Free of moral guilt.
Answered prayer.
Inner witness of Holy Spirit.
Hearing God’s word through preaching.
Love for God.
Belief Jesus is the Christ.
Belief in God’s record/testimony.
Encouraging for believers (“yes” to most/all); sobering for those with no evidence.
Exposition: 1 John 1:1–4
v. 1 — “That which was from the beginning…” (echoes John 1:1 — Christ eternal Word/God).
Personal eyewitness: Heard, seen, looked upon, touched → emphasizes full humanity.
“Word of life” = Christ (eternal life manifest).
v. 2 — Life “made manifest” (revealed openly); apostles testify/proclaim eternal life (with Father, now to us).
v. 3 — Proclaim so readers have fellowship (koinonia — close relationship) with apostles → ultimately with Father and Son Jesus Christ.
v. 4 — Written so “our joy” (or “your joy”) may be complete/full.
Key emphases:
Jesus: Fully God (eternal, with Father) + fully man (physical senses experienced).
Against heresies denying humanity (e.g., Gnostics/Docetists claiming Christ only “seemed” human; matter evil → no true incarnation).
Humanity essential for:
Substitutionary atonement (Hebrews 2:9, 14–18 — tasted death as man; destroy devil’s power; merciful high priest; sympathize with tempted).
Perfect obedience (fulfill law as last Adam).
Example of holiness.
Purpose: Proclaim for fellowship (with God, believers) → leads to complete joy.
Closing Prayer Emphasis
Thanks for God’s Word through John.
Help apply truths today.
Gratitude: Jesus fully God + fully human → perfect sacrifice for atonement.
Focus on assurance through evidence of faith, Christ’s dual nature, and joyful fellowship.
