The Origin They Missed (7:25–31)
Israel’s hope for a Messiah took on a particular form. By the Second Temple period, many Jews believed that when the Messiah finally arrived, his origins would be concealed, and his true identity would remain hidden until the moment he suddenly appeared and was revealed. It was this hiddenness that would define him—no one would see him coming.
This expectation appears in several texts from that period: the figure rising from the sea in 4 Ezra is hidden and unknown until his revelation (4 Ezra 13:51–52), the Son of Man in 1 Enoch is described as chosen and concealed from God before creation (1 En. 48:6), and Justin Martyr’s second-century dialogue with Trypho preserves the tradition that the Messiah remains unknown even to himself until Elijah comes to reveal him (Justin Martyr, Dial. 8.4).
The Jerusalem crowd in John 7 is aware of this tradition, and they use it to settle the question of Jesus once and for all.
“But we know where this man comes from, and when the Christ appears, no one will know where he comes from” (John 7:27).
The logic appears sound. They believe Jesus is from Galilee, yet the Messiah’s origins are meant to be unknown. So, Jesus cannot be the Messiah. Case closed.
John, however, is doing something precise here. The crowd is correct that the Messiah’s origins would be concealed from them. They are simply mistaken about which origins are important. Jesus responds with sharp irony:
“You know me, and you know where I am from. But I have not come of my own accord. He who sent me is true, and him you do not know. I know him, for I come from him, and he sent me” (John 7:28–29).
The geographic location, Galilee, isn’t the main point. The important origin is the Father, who is completely hidden from them. They dismiss Jesus based on a tradition that, applied correctly, would have identified him. The crowd reaches for the right criterion and misses the right answer.
This pattern runs throughout John’s Gospel. Characters often speak more truth than they realize. Caiaphas later states it is more convenient for one man to die for the people, meaning something much smaller than what John records (John 11:49–52). Pilate asks, “What is truth?” while standing in front of it (John 18:38). The Jerusalem crowd references the hidden Messiah and describes him perfectly without actually recognizing him.
Jesus’s true origin is not a village in Galilee. It is the Father who sent him. And because they do not know the Father, they cannot recognize the Son. The hiddenness they expected was always theological, not geographical. The Messiah came from exactly where no one was looking.
The Water that Waits (7:37–39)
Israel had not forgotten the rock. In the wilderness, when the people were dying of thirst, God told Moses to strike it, and water poured out to sustain the whole congregation (Exod 17:6). The memory of that moment shaped the Feast of Booths, which commemorated God’s provision during the wilderness years. Each morning of the feast, priests drew water and carried it in procession to the temple, enacting Israel’s hope that God would provide once again.
But the prophets had promised something greater than water from a rock. Zechariah had envisioned a day when living waters would flow from Jerusalem itself (Zech 14:8). Isaiah had made an explicit connection between water poured on the land and the Spirit poured on God’s people: “I will pour water on the thirsty land, and streams on the dry ground; I will pour my Spirit upon your offspring” (Isa 44:3). The wilderness provision pointed forward to a final, eschatological outpouring.
On the final and most important day of the Feast of Booths, Jesus stands and proclaims boldly, using language unique to John’s Gospel:
“If anyone thirsts, let him come to me and drink. Whoever believes in me, as the Scripture has said, ‘Out of his heart will flow rivers of living water’” (John 7:37–38).
Jesus appears to quote the Old Testament, although his exact words aren’t found in any single passage. He is summarizing a broad stream of prophetic hope, from the water at the rock to Zechariah’s vision of living water flowing from the eschatological Jerusalem. He has already described himself as the bread of life (John 6); now he portrays himself as the source of living water. He is both the typological fulfillment of what God did in the wilderness and the direct fulfillment of what the prophets envisioned.
John then provides the interpretive key: “Now this he said about the Spirit, whom those who believed in him were to receive, for as yet the Spirit had not been given, because Jesus was not yet glorified” (John 7:39). Glorification here means resurrection and ascension. The living water cannot flow until Jesus has passed through death, been raised, and seated at the Father’s right hand. When that moment arrives, the Spirit falls on Jerusalem, the followers of Jesus are filled, and the eschatological outpouring the prophets foretold finally occurs (Acts 2).
Jesus embodies Israel’s entire story and brings it to its climax. The water from the rock always pointed here. Give thanks today for the Holy Spirit. His presence in you is living water, cleansing, refreshing, and renewing.
