Exposition of John Chapter 1: The Gospel of Jesus Christ

John's Gospel opens with a declaration of cosmic scope: "In the beginning was the Word, and the Word was with God, and the Word was God" ^[8]. This prologue echoes Genesis 1:1, anchoring the narrative of Jesus Christ in the eternal purposes of God before creation itself. The evangelist identifies Jesus as the divine Logos—pre-existent, co-equal with the Father, and the agent through whom all things came into being. The cross-references to this verse span from Isaiah's prophecies of the divine child (Isaiah 7:14, 9:6) to Paul's affirmation in Philippians 2:6 and the closing vision of Revelation, where Christ declares himself "the Alpha and the Omega" ^[8].

The Incarnation and Glory

The prologue reaches its climax in verse 14: "The Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father." This manifestation of divine glory in human form is central to John's purpose. As Torrey's Topical Textbook notes, God's glory is "exhibited in Christ" ^[7], fulfilling what Moses glimpsed on Sinai and what the prophets foretold. The verb "dwelt" (literally "tabernacled") evokes the wilderness sanctuary where God's presence rested among Israel—now incarnate in a person.

John the Baptist appears as the forerunner, bearing witness to the Light. Mark's Gospel identifies this as "the beginning of the gospel of Jesus Christ" ^[1], and Matthew Henry observes that the gospel narrative properly commences with John's baptism, "for then Christ began first to appear in him, and then to appear to him, and by him to the world" ^[12]. The Baptist's testimony is emphatic: he is not the Light but came to bear witness to the Light. His role is preparatory, pointing beyond himself to the one whose sandal he is unworthy to untie.

Authorship and Purpose

The apostle John wrote this Gospel, likely at Ephesus in his advanced age—estimates range from A.D. 78 to the close of the first century ^[5]. Easton's Bible Dictionary affirms that "the genuineness of this Gospel, i.e., the fact that the apostle John was its author, is beyond all reasonable doubt" ^[2]. Unlike the synoptic Gospels, which concentrate on Jesus' Galilean ministry, John supplements their accounts with extended discourses and events in Judea and Jerusalem ^[5]. His stated purpose appears in John 20:31: that readers "may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name."

The Gospel's opening verses establish themes that recur throughout: light and darkness, witness and testimony, belief and unbelief. John Gill notes that this narrative "began with the ministry" of John the Baptist, though the gospel message itself was proclaimed as early as Eden and to Abraham ^[9]. The evangelist writes not primarily for unbelievers but for the Church, "to cultivate and cherish the spiritual life of Christians, and bring them into the closest relations to the divine Savior" ^[5].

Witness and Fellowship

The apostle's emphasis on eyewitness testimony connects the Gospel to his first epistle, where he writes of "that which was from the beginning, which we have heard, which we have seen with our eyes, which we looked upon and have touched with our hands, concerning the word of life" ^{[4, 11]}. This insistence on tangible, historical encounter grounds Christian faith in verifiable events. The purpose of such testimony is fellowship—union with the Father and the Son ^{[3, 10]}. As Jamieson, Fausset & Brown observe, "As the Son announced the message heard from the Father as His apostle, so the Son's apostles announce what they have heard from the Son" ^[13].

The declaration that "God is light, and in him is no darkness at all" ^[13] establishes the moral framework for the entire epistle. To claim fellowship with God while walking in darkness is to lie ^[6]. The incarnate Word reveals not only divine glory but divine holiness, calling believers to walk in the light as he is in the light.

The purpose of the apostle (1:1-4) is to declare the Word of Life to those to whom he writes, in order that they might be united in fellowship with the Father and his Son Jesus Christ. He shows that the means of union with God are, (1) on the part of Christ, his atoning work (1:7; 2:2; 3:5; 4:10, 14; 5:11, 12) and his advocacy (2:1); and (2), on the part of man, holiness (1:6”

There can be little doubt that the main object of St. John, who wrote after the other evangelists, is to supplement their narratives, which were almost confined to our Lord's life in Galilee.
