The next day John saw Jesus coming toward him and said, “Look, the Lamb of God, who takes away the sin of the world! This is the one I meant when I said, ‘A man who comes after me has surpassed me because he was before me.’ I myself did not know him, but the reason I came baptizing with water was that he might be revealed to Israel.” Then John gave this testimony: “I saw the Spirit come down from heaven as a dove and remain on him. And I myself did not know him, but the one who sent me to baptize with water told me, ‘The man on whom you see the Spirit come down and remain is the one who will baptize with the Holy Spirit.’ I have seen and I testify that this is God’s Chosen One.” (John 1:29-34)
Right on cue, the next day, Jesus and John the Baptist cross paths. You get the sense that this scene takes place a few days or weeks, perhaps, after John baptizes Jesus in the Jordan River. The other Gospels – Matthew, Mark, and Luke – all record the event. John’s Gospel only refers to the baptism, and instead recounts this scene of a few days or weeks later.
John exclaims when he sees Jesus, and says “I myself did not know him” twice. Once, perhaps to the few gathered near him, and then a second time in a more formal declaration to a wider audience.
The second time the writer introduces John the Baptist’s pronouncement of “I myself did not know him” with the phrase “then John gave this testimony.” He is elated that the fulfillment to his mission is within view, and that the way it was revealed to him was not only surprising to him – but delighted him.
Lamb of God
Many have commented that John is comparing Jesus to a Passover lamb, or to a sacrificial lamb for the sins of the people, or perhaps even the concept that Jesus was to be led like a lamb to the slaughter when he is crucified. These references seem plausible, but not entirely satisfactory. In fact, “Lamb of God” may not have been too compelling to most of John the Baptist’s own followers. He makes the reference twice, and only on the second occasion do a mere two of his disciples think enough of it to leave him and follow Jesus.
The rest of the first chapter indicates a small and intimate band of followers of Jesus. “Lamb of God” is curious because it is presumably the opposite description his audience is expecting. The messiah was anticipated as a conqueror whose primary aim would be to promote Israel’s interests and sovereignty. But John goes on to say that Jesus as the “Lamb of God” was going to take away the sin of the world – not merely the sin of Israel.
In their book, Social Science Commentary on the Gospel of John, Malina and Rohrbaugh are convinced that the author is referencing what is actually the celestial star formation known to a Latin and Greek audience as Aries the Ram, and similarly to the Hebrew audience as Tale’. If they are correct, then the metaphor may not have been viewed as quite so unusual.
Perhaps all those meanings for “Lamb of God” are true in some sense. In any case, aside from the summary of the first 18 verses, this is the first of an extensive series of metaphors applied in the book of John to Jesus. In the case of most, the phrase “for the world” is added or that concept is inherent.
Testimony
The word “testimony” is very important and used often in this book. John the Baptist in this passage gives testimony a number of times. First, his testimony is “I am not the one.” Later, his testimony is “Jesus is the one.” This testimony that John gives on Jesus’ behalf is referred to later in the book. Several times indirectly, and at least once directly. The word is used in a manner to convey a solemn oath.
Along with the concept of testimony throughout, you also read that Jesus many times uses introductory phrases like “Very truly I tell you” or “I tell you the truth.” Other translations use “Verily, verily.” The phrase was literally “Amen, Amen.” You get the sense that Jesus is saying “Listen very carefully, this is supremely important.” More on that later.
Spirit
Spirit is another important word in the Gospel of John. Jesus emphasizes the importance of the Spirit over and over again throughout. Here John the Baptist announces that he saw the Spirit come down on Jesus and remain on him, and that Jesus would be the one who would baptize with the Spirit – as opposed to merely with water.
Identity
The identity of Jesus is of utmost importance to John’s Gospel. Almost every chapter or new scene introduces a new metaphor introducing another concept about who he really is. He has long-running arguments with the Jewish leaders about his true identity. You get the sense that the author believes that if you can just believe who he truly is, everything else will fall into place.
So John says “I am not the one” but Jesus is, and in his office as “God’s Chosen One” he will be taking away the sin of the entire world (not just Israel) and will be bringing God’s Spirit to those who follow him.
In the next scene, we will see his first disciples begin to follow Jesus, and yet again, their expectations of who is he is, and what his mission will be, are “adjusted.”
