Day 1: The High Priestly Prayer

Reading: John 17

Listen to: John chapter 17

Historical Context

John 17 has been called “the Holy of Holies of the New Testament” by scholars from the Reformation to the present, and the title is fitting. On the Day of Atonement, the high priest of Israel entered the Most Holy Place – the innermost sanctum of the temple – to intercede for the people before the very presence of God. Only one person could enter, only once a year, and only with sacrificial blood (Leviticus 16). In John 17, Jesus assumes the role of the true High Priest, but instead of entering a sanctuary made with hands, he lifts his eyes to heaven and speaks directly to the Father in the hearing of his disciples. There is no veil between them. The intimacy is staggering. And unlike the Levitical high priest, who interceded for Israel’s sins with the blood of goats and bulls, Jesus intercedes with the offering of his own life, which he is about to surrender on the cross.

The prayer falls into three natural movements. In verses 1-5, Jesus prays for himself – or more precisely, for the glorification of the Father through the completion of his mission. “Father, the hour has come; glorify your Son that the Son may glorify you.” Throughout John’s Gospel, “the hour” has been a loaded term, pointing forward to the crucifixion (2:4; 7:30; 8:20; 12:23, 27; 13:1). Now it has arrived. Jesus does not pray for escape but for the consummation of his work. The “glory” he requests is not the avoidance of suffering but the manifestation of God’s character through suffering. He prays to be restored to “the glory that I had with you before the world existed” (17:5) – a statement that reaches back past the incarnation, past creation itself, into the eternal communion of Father and Son. This is the only place in the Gospels where Jesus explicitly speaks of his pre-incarnate glory, and it confirms what John declared in the prologue: “In the beginning was the Word, and the Word was with God, and the Word was God” (1:1).

The prayer’s most theologically significant definition comes in verse 3: “And this is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent.” Eternal life, in this formulation, is not primarily a quantity of time (living forever) but a quality of relationship (knowing God). The verb “know” (ginoskein) in biblical usage implies intimate, experiential, covenantal knowledge – the kind of knowledge that exists between marriage partners, not the kind that exists between a student and a textbook. Eternal life begins not at physical death or at the Second Coming but at the moment a person enters into this relational knowledge of God through Jesus Christ.

In verses 6-19, Jesus prays for his disciples. The petitions are profoundly specific. He prays that the Father would “keep them in your name” – that is, preserve them in the sphere of divine identity and protection. He prays for their unity, “that they may be one, even as we are one” – a unity modeled not on organizational structure or doctrinal uniformity but on the relational unity of the Trinity itself. He prays for their protection from “the evil one” – recognizing that the disciples will face spiritual opposition of a personal, intelligent, and malicious kind. And he prays for their sanctification: “Sanctify them in the truth; your word is truth” (17:17). Sanctification here is not moral improvement in the abstract but being set apart by truth for a mission. The disciples are being consecrated – like priests being dedicated for temple service – for the task of carrying Jesus’ word into a hostile world.

The prayer’s final section (verses 20-26) extends beyond the upper room to encompass every person who will ever believe in Jesus through the apostles’ testimony – which means it includes every Christian who has ever lived and every Christian who ever will live. “I do not ask for these only, but also for those who will believe in me through their word” (17:20). When Jesus prays in Gethsemane, he is praying for first-century fishermen and twenty-first-century office workers, for African martyrs and Asian house church leaders, for medieval mystics and Reformation theologians. The scope is breathtaking. And the central petition for this vast company of believers is unity: “that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me” (17:21). The purpose of Christian unity is not institutional harmony for its own sake; it is missional witness. The world is meant to see the love and unity of Christ’s followers and conclude that Jesus was indeed sent by God. Division among Christians is therefore not merely a regrettable social problem; it is a contradiction of the prayer of the Son of God and an obstacle to the world’s belief.

Jesus closes with a declaration of love that spans eternity: “Father, I desire that they also, whom you have given me, may be with me where I am, to see my glory that you have given me because you loved me before the foundation of the world” (17:24). The ultimate destiny of the believer is not a place called heaven but a relationship of sight – seeing Christ’s glory, beholding the love that existed between Father and Son before anything else existed. The prayer that began with glory ends with glory, and at its center is the love that holds all things together.

Key Themes

• Eternal life as knowing God – Eternal life is defined not as endless duration but as intimate, relational knowledge of the Father through Jesus Christ
• Priestly intercession – Jesus fulfills the role of the true High Priest, interceding for his people with the offering of his own life
• Unity as mission – The unity of believers, modeled on the unity of the Trinity, serves as the primary witness to the world that Jesus was sent by the Father

Connections

• Old Testament Roots: Leviticus 16 (the Day of Atonement and the high priest’s intercession); Exodus 28-29 (the consecration of priests); Deuteronomy 33 (Moses’ blessing/prayer for the tribes of Israel)
• New Testament Echoes: Hebrews 7:25 (“he always lives to make intercession”); Romans 8:34 (“Christ Jesus is the one who… is interceding for us”); Ephesians 4:1-6 (“eager to maintain the unity of the Spirit”)
• Parallel Passages: John 14:16-17; Hebrews 7:25; Romans 8:34

Reflection Questions

1. How does Jesus’ definition of eternal life in John 17:3 challenge or expand your understanding of what it means to have eternal life?
2. Jesus prays for his disciples to be “in the world” but “not of the world” (17:11, 14-16). What does this tension look like in your daily life, and how do you navigate it?
3. Jesus’ prayer for unity (17:20-23) has a missional purpose: “so that the world may believe.” How seriously does your faith community take the connection between internal unity and external witness?

Prayer

Father, we are awed to overhear your Son praying for us – not just for the Twelve in that upper room but for all who believe through their testimony. Thank you that eternal life is not a distant reward but a present relationship, the gift of knowing you. Protect us from the evil one. Sanctify us in your truth. Make us one, as you and your Son are one, so that the world might see and believe. May we one day behold the glory you gave your Son before the world began. Amen.
