The Meaning of John 8:28: Lifted Up, Fully Known

Understanding Jesus' Hour of Exaltation

This verse comes during a tense exchange between Jesus and skeptical religious leaders in the temple courts, where He speaks plainly about His identity and mission.

Jesus has been teaching in Jerusalem, and the tension is rising as the leaders challenge His authority. He tells them that when they 'lift up the Son of Man' - a phrase that means both His crucifixion and His exaltation - they will finally see who He really is. The title 'Son of Man' in Daniel 7:13-14 refers to a heavenly figure who receives eternal dominion, indicating that Jesus is the promised ruler from God, not merely a teacher.

His death on the cross will not be a defeat, but the moment His true identity is revealed and His unity with the Father made clear to all.

The Divine 'I Am' and the Meaning of Being Lifted Up

Jesus’ words in John 8:28 are far more than a prediction - they carry the weight of divine identity and purpose, deeply rooted in the Old Testament and layered with meaning that would only become clear after the cross.

The phrase 'I am he' is more than a simple declaration; it echoes Isaiah 43:10-11, where God says, 'You are my witnesses… I am he.' Before me no god was formed, nor will there be one after me. I, even I, am the Lord, and apart from me there is no savior.' By using this same language, Jesus is quietly claiming to be the very God of Israel standing among them. In a culture where honor was tied to authority and divine backing, this would have been both shocking and deeply significant. The religious leaders expected a prophet, but Jesus speaks with the authority of the One who sent all prophets.

The phrase 'lifted up' carries a triple meaning: it refers to Jesus being lifted up on the cross, as He explains in John 12:32-33, but also to His exaltation and glorification. In the ancient world, crucifixion was the most shameful death possible - reserved for rebels and slaves. Yet Jesus redefines it as the moment of His highest honor. This irony would not be lost on John’s readers, many of whom lived under Roman rule and knew the brutal reality of execution. To them, 'lifted up' would sound like defeat to the world, but in God’s economy, it is the moment of victory and revelation.

Jesus also says He does nothing on His own authority, echoing John 5:19. In that verse He states, 'The Son can do nothing by himself and can only do what he sees his Father doing.' This shows His complete unity with the Father - not as a separate god acting alone, but as one in purpose and nature. His words are not His own ideas but come straight from the Father’s teaching.

This moment points forward to the resurrection, when even those who rejected Him would begin to see the truth. The cross becomes the turning point where misunderstanding gives way to recognition - only after Jesus is lifted up will many finally know that He is who He claimed to be.

Jesus as the Faithful Messenger Sent by the Father

This moment in John’s Gospel highlights the book’s purpose: Jesus is not merely a wise teacher but the one sent from God to reveal the Father’s heart and will.

He speaks not from human insight but directly from the Father’s teaching, just as He says in John 12:49-50: 'For I did not speak on my own authority, but the Father who sent me has himself given me a commandment - what to say and how to say it. I know that his commandment is eternal life. The things I speak, therefore, I speak just as the Father has told me.' This shows Jesus as the perfect messenger, completely aligned with God’s purpose.

I do nothing on my own authority, but speak just as the Father taught me

John’s Gospel keeps returning to this truth - that Jesus is the Word made flesh, the one who reveals God in a way no one else ever has. The cross, then, is not the end of His mission but its climax. It forces a decision: will we see Jesus as merely a man, or as the one sent from heaven? The timeless truth here is that God’s greatest revelation comes not in power or spectacle, but in humble obedience - and it’s at the cross that we finally see who God really is.

The Bigger Story: How Jesus Fulfills the Old Testament

This moment in John 8:28 is more than a turning point in Jesus’ ministry; it is the climax of a story that began in the Old Testament.

Jesus’ words about being 'lifted up' echo John 3:14, where He says, 'Just as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, that whoever believes in him may have eternal life.' In Numbers 21, God told Moses to raise a bronze serpent on a pole so that anyone who looked would be healed from deadly snake bites. Jesus says He is the true serpent - lifted up not merely to heal, but to save completely. This is not just a clever comparison; it’s Jesus claiming to be the fulfillment of that ancient event.

The 'I Am' statements throughout John - like 'I am the bread of life' (6:35), 'I am the light of the world' (8:12), and 'I am the gate' (10:7) - all build toward this moment when Jesus quietly declares divine identity with 'I am he,' echoing God’s own words in Isaiah 43:10-11: 'I, even I, am the Lord, and apart from me there is no savior.'

Jesus also speaks not from His own ideas but as the Father taught Him, a theme repeated in John 7:16 ('My teaching is not my own'), John 8:38 ('I speak just what the Father has taught me'), and John 12:49-50, where He says the Father gave Him exactly what to say. This shows He is not merely a prophet, but the perfect Word of God. In Acts 2:36, after the resurrection, Peter declares, 'God has made this Jesus, whom you crucified, both Lord and Christ,' proving that the recognition Jesus foretold in John 8:28 finally came true.

When you have lifted up the Son of Man, then you will know that I am he

So this verse is more than about a future event; it is the key that unlocks how Jesus fulfills the whole Bible: He is the true serpent, the divine 'I Am,' the faithful Son who speaks God’s words, and the crucified Messiah now declared Lord. The cross, once a sign of shame, becomes the moment the world begins to see who He really is.
