“The hour has come for the Son of Man to be glorified” (John 12:23). So Jesus says to Andrew and Philip, who come with a request from “some Greeks” who were in Jerusalem for the festival of Passover (12:20; see 12:1). See https://johntsquires.com/2021/03/15/we-wish-to-see-jesus-john-12-lent-5/
Two terms in this declaration by Jesus require exploration; two terms which are key ideas in this Gospel, the book of signs.
The story which John’s Gospel reports contains a contrast between the largely public activities of Jesus, and a secret element, described as “the hour”, which does not come until the climax of the story is reached. There are pointers to this contrast from the very first sign, at a wedding in Cana, when Jesus declares, “my hour has not yet come” (2:4).
What is this hour? The first part of the Gospel leaves it as a mystery, for the time being (see 7:30 and 8:20). Then, after the seventh sign, events in Jerusalem show that the hour has come (12:23, 27); the narrator explains that “Jesus knew that his hour had come to depart from the world” (13:1).
Thus, at the beginning and at the end of the public activities of Jesus in this Gospel narrative, the focus is firmly on “the hour”.
Then, some time later on, at the end of his last meal with his followers, Jesus finally prays: “Father, the hour has come: glorify your Son” (17:1). In what will take place after this prayer—the arrest, trial, crucifixion, burial, and resurrection of Jesus (John 18–21)—this “hour” is realised.
The Johannine Jesus describes these events, the fulfilment of “the hour”, as the means by which God is glorified (11:16, 23–33; 13:31–32; 17:4).
The word “glory”, in Hebrew Scriptures, signals the divine presence (Exod 16:1–12; 24:15–18; 40:34–39; Lev 9:22–24; Num 14:10–12; 16:19; Deut 5:22–27; 1 Sam 4:19–22). In the book of signs, it is God’s glory which is now made manifest in Jesus (John 1:14; 2:11; 12:27–28; 17:5).
The language of “hour” and “glory” thus provides a framework for interpreting the events in chapters 2–12 as steps on the way towards a full understanding of Jesus, and the events of chapters 13–21 as the realisation of God’s presence in the world in all its fullness. This is the heart of the incarnational theology that is advocated by the writer of this Gospel.
The story of the Gospel fills out the details as to how it is that “the Word became flesh and lived among us”, which means that for human beings, “we have seen his glory, the glory as of a father’s only son, full of grace and truth” (John 1:14).
The passage offered in this Sunday’s lectionary readings provide part of the Johannine account of the final public moments of Jesus before his arrest (12:20–50). Here, Jesus speaks of this imminent glory (12:20–26), an angel testifies to God’s glory in the death of Jesus (12:27–33), Jesus explains that he comes as light into the world (12:34–36), the scriptures join as witnesses (12:37–43) and Jesus asserts that he speaks God’s commandment of eternal life (12:44–50).
This scene sums up what has come before and opens the door to the events which follow, culminating in the cry of the crucified Jesus, “it is fulfilled” (19:30; the NRSV translation, “it is finished”, downplays the sense of fulfilment in the verb used, teleō). The author of this Gospel thereby indicates that the deepest fulfilment of the hour of Jesus comes on the cross, as the glory of God is revealed in its entirety.
