“John Testifies About Jesus” (1:29–34)

T. W. Parker

(John. 1:29). The phrase “Lamb of God” is a distinctive expression found in the Bible only here and in verse 36. This uniqueness highlights the profound significance of Jesus’ mission, which is unlike any other. Various interpretations have been suggested regarding which “lamb” John refers to—whether it be the Passover lamb, the lamb mentioned in Isaiah 53:7, Jeremiah 11:19, Genesis 22:8, or Revelation 5:6. However, it seems that John deliberately chose this particular phrasing to illustrate both the sacrificial offering Jesus would become. His eventual triumph over all evil powers (see Revelation 17:14). These two aspects reflect how He “takes away the sin of the world” (John 1:29). Additionally, see 1 John 2:2 for further context.

(John. 1:30). Here John repeats what he said earlier about Jesus (vs. 15, 27). John’s fame was to be superseded by that of Jesus, whose priority stems from His preexistence: Moreover, it is the reason John stated, “He was before me” (vs. 1:30).

(John. 1:31). Yet, why did John say, ‘I myself did not know Him? Although John and Jesus were related, as Mary and Elizabeth were relatives (Luke 1:36), no information is available about any contact between them during their childhood or adolescence. As a result, John did not realize that Jesus was the coming One until the Father revealed Him. This divine revelation is a testament to the unfolding of God’s plan. John only knew that he was to prepare the way for Him by baptizing with water. Yet, God would reveal Him to Israel at His appointed time.

(John. 1:32). The baptism of Jesus is not recorded in John’s Gospel, but the material of the Synoptic Gospels is assumed. The significant thing is that the invisible Spirit came from heaven and manifested Himself in a bodily (dovelike) form. John saw the Spirit as a dove remaining on Jesus (Isa. 11:2, Mark 1:10).

(John. 1:33). John baptized with water, but Jesus would baptize with the Holy Spirit, by which He would cause those who believe in Him to participate in the power and grace of the new life He came to give (see. John. 20:22, Acts. 1:5, 2:4, 11:15-16, 19:4-6, 1 Cor. 12-14, Gal. 3:5, 14, 4:6, 5:16-25, Eph. 1:13, 3:16, 5:18, Phl. 3:3, 1Th. 4:8). The standard way of referring to the Spirit in the (NT). However, it appears only here and in (John 14:26, 20:22) in this Gospel, emphasizing His holiness rather than His power or greatness.

(John. 1:34). Indeed, John’s testimony was “that this is the Son of God.” The prophesied Davidic King was God’s Son (2 Sam. 7:13), and the messianic King is uniquely the Son of God (Ps. 2:7). The title “Son of God” goes beyond the idea of obedience and messianic King to that of Jesus’ essential nature. For this reason, in the Fourth Gospel, this title is not applied to believers. They are called “children” (John. 1:12), while “Son” (hyios) is used only of Jesus!

Final thought:
We are called to “behold the Lamb of God” by recognizing Jesus as the ultimate sacrifice for our sins, which allows us to be forgiven and restored to a relationship with God. As believers, we are also encouraged to live as witnesses to His truth, sharing the good news of the Lamb through both our words and our actions, while continually seeking spiritual nourishment from Christ. Furthermore, we should embrace God’s revelations in our lives, trust in His faithfulness, and live with courage and resolve, empowered by the Holy Spirit.
