Foreshadowing Jesus in the Book of 1 John

1. Introduction: Overview of the Book and Its Foreshadowing Themes

• Book Overview:
  1 John, traditionally attributed to the Apostle John, was written around AD 85–95 to strengthen believers in their assurance of eternal life and to combat false teachings, particularly early forms of Gnosticism. The letter presents Jesus Christ as the incarnate Son of God, the eternal life made manifest, the light of the world, the advocate for sinners, and the righteous one. It stresses the inseparable connection between sound doctrine, moral living, and brotherly love.
  • Key Verse:
    1 John 5:12 – “Whoever has the Son has life; whoever does not have the Son of God does not have life.”
• Foreshadowing Themes:
  1 John presents Jesus as the fulfilment of Old Testament images of light, righteousness, advocacy, and sacrificial atonement. The language of “light versus darkness,” “love,” and “truth” echoes the character of God as revealed through the Law and the Prophets, now fully embodied in Christ.
  • Key Verse:
    1 John 1:5 – “God is light; in Him there is no darkness at all.”

2. Historical and Theological Context

• Historical Context:
  Written in the context of rising false teachings that denied Jesus’ true humanity or divinity, 1 John counters with strong affirmations of the incarnation. John addresses a community shaken by schisms and confusion, offering reassurance and doctrinal clarity centred on the person of Jesus.
  • Key Verse:
    1 John 2:26 – “I am writing these things to you about those who are trying to lead you astray.”
• Theological Context:
  Theologically, the epistle underscores the reality of the incarnation, the necessity of righteous living, and the call to love as evidence of new birth. Jesus is the perfect expression of God’s nature—eternal, incarnate, righteous, and sacrificial. Believers are called to abide in Him and live as He lived.
