The story of Jesus walking on water is so familiar that many of us no longer read it carefully.
We know the outline. The disciples are caught in a storm. The wind is against them. The waves are crashing around their small fishing boat. Then, in the darkness before dawn, Jesus comes walking across the sea.
It is one of the most famous miracles in the Gospels.
For most readers, the point seems obvious. Jesus demonstrates his power over nature, the disciples are amazed, and Peter’s brief attempt to walk on water teaches us something about faith and doubt.
Yet hidden in the middle of the story is a detail that feels completely out of place.
It is so strange that many readers pass over it without a second thought.
Mark tells us that Jesus came towards the disciples, walking on the water. Then he adds a sentence that raises more questions than it answers:
“He was about to pass by them.” (Mark 6:48)
Wait, he passed by them?
The more you think about it, the stranger it becomes.
The disciples are exhausted. They have been struggling against the wind for hours. Jesus sees their distress. He walks across the lake towards them, and everything appears to be building towards a rescue.
Then Mark tells us that Jesus intended to pass by.
Was he planning to ignore them? Was he simply crossing the lake and happened to notice them on the way? Was he somehow trying to teach them a lesson?
None of those explanations feels convincing. Mark has deliberately included this detail, and Gospel writers rarely waste words.
The clue lies in a pattern that runs through the Old Testament.
When God “passes by” someone, something important is usually about to happen.
When God Passes By
One of the clearest examples of this occurs in Exodus.
After Israel’s rebellion with the golden calf, Moses asks to see God’s glory. To be fair, it is an audacious request. Moses does not simply want guidance or reassurance. He wants a deeper encounter with the God he serves.
God responds by placing Moses in the cleft of a rock and declaring:
“I will cause all my goodness to pass in front of you.”
What follows is not that God is travelling from one place to another. He is revealing himself. Moses receives a glimpse of God’s character, God’s presence, and God’s glory.
Centuries later, something remarkably similar happens to Elijah.
The prophet is exhausted, disillusioned, and hiding on Mount Horeb. There, he receives a command to stand before the Lord because the Lord is about to pass by.
A violent wind tears through the mountains. An earthquake follows. Then fire. Yet God is not found in any of these dramatic displays. Instead, Elijah encounters the divine presence in a gentle whisper.
Once again, God passes by.
In both stories, the phrase has little to do with movement and everything to do with revelation. God is making himself known.
It is that observation that transforms the story in Mark.
If this pattern is intentional, then Jesus is not trying to avoid the disciples at all. The story does not describe a failed rescue attempt or a curious travel route across the lake. It describes a moment of revelation hidden within a miracle story.
Perhaps what Jesus is really trying to do is to reveal himself to them.
The more we explore the story, the stronger that possibility becomes.
The Connection to Job
Another clue appears in the book of Job. Speaking about God, Job describes the one who “treads on the waves of the sea”. A few verses later, he laments that God “passes by” and cannot be fully perceived.
The parallels are clear. God walks upon the waters. God passes by. Human beings struggle to recognise what is happening before their eyes.
Suddenly, Mark’s story no longer feels like an isolated miracle account. It begins to sound like a beautiful echo of Israel’s Scriptures.
Jesus is not merely doing something impressive. He is doing things that the Old Testament repeatedly associates with God himself.
That might change the question we bring to the passage.
Instead of asking how Jesus walked on water, Mark seems to be inviting us to ask who Jesus is.
The Sea Was Never Just Water
This becomes even more significant when we remember what the sea represented in the ancient Jewish world.
To modern readers, water is simply part of the natural world. To ancient Israel, the sea often symbolised chaos, danger, and forces beyond human control. Throughout Scripture, God’s power is displayed in his mastery over these threatening waters. He separates the waters in creation, parts the Red Sea in the Exodus, and repeatedly demonstrates his authority over the deep.
The Psalms celebrate God’s rule over the raging sea. The prophets describe him trampling the waves. Again and again, the message is the same: chaos does not have the final word because God remains sovereign over it.
Only God rules the chaos.
Only God can walk unharmed through the waters.
Against that backdrop, Jesus calmly crossing the sea takes on an even deeper significance. The miracle is not merely a suspension of natural law. It is a visual statement about identity.
The disciples, however, fail to grasp it.
The Tragedy Hidden in the Boat
In fact, Mark’s account ends on a surprisingly sombre note. After Jesus enters the boat, Mark explains that the disciples were utterly astonished because they had not understood about the loaves. Their hearts were hardened.
At first glance, this feels confusing. What do loaves have to do with walking on water?
Everything, according to Mark.
The feeding of the five thousand had already revealed something profound about Jesus. He had provided abundance in the wilderness where there should have been scarcity. He had acted like the shepherd of God’s people and demonstrated a divine generosity that should have prompted deeper reflection.
The disciples had not merely heard about the miracle. They had participated in it, distributing the food, gathering the leftovers, and witnessing thousands of people fed from what should have been an impossibly small amount.
Yet Mark says they still did not understand.
This suggests the feeding miracle was also never simply about food. Just as God provided manna in the wilderness, Jesus provided abundance where there should have been none. Just as God shepherded Israel through the desert, Jesus shepherded the crowds. The miracle pointed beyond itself.
Now the disciples are making the same mistake again. They see the miracle but miss the meaning.
Perhaps that is the real tragedy of the story. The disciples are not struggling because they lack evidence. They are struggling because they do not yet recognise what the evidence before them points to.
The story is not ultimately about water.
It is about recognition.
The Words We Often Miss
Even Jesus’ words point in the same direction.
When he calls out across the waves, our English translations usually render his words as:
“It is I.”
Yet the Greek expression is simply:
“I am.”
Those words inevitably echo God’s self-revelation to Moses at the burning bush. Whether Mark intends readers to hear the full implication of that connection is debated, but the cumulative effect of the story is difficult to ignore.
By this point, the clues are beginning to accumulate. Jesus walks upon the sea, intends to pass by in language that echoes the Old Testament, and speaks words that recall God’s self-revelation to Moses. The story keeps pointing in the same direction.
The clues keep pointing in the same direction. No wonder the disciples are overwhelmed and that they struggle to make sense of what they are seeing.
Matthew’s Gospel adds the famous episode of Peter stepping out onto the water. It is a powerful story in its own right, and one I explored in a
. Yet before Peter ever climbs over the side of the boat, there is another question lurking beneath the surface of the story.
Who is the person standing on the waves?
Mark’s focus is not primarily on Peter’s faith or failure. It is on the identity of Jesus. The miracle is not simply an invitation to trust more deeply. It is a revelation of the one in whom that trust is placed.
Recognising Who Is Present
Perhaps that is why this story still speaks so powerfully today.
We often imagine that our greatest challenge is surviving the storm. I have had periods in my own life when everything around me seems to be in chaos. Things are going wrong, and nothing can be controlled. In the middle of that storm, I have, of course, prayed for the storm to stop.
There is, of course, nothing wrong with this. We pray for solutions, clarity, healing, and safe passage. The disciples certainly wanted the wind to stop.
Yet Mark suggests that something even more important may be happening.
Before Jesus calms the sea, he reveals himself upon it.
Before he changes their circumstances, he confronts them with a question about his identity.
That is often the harder lesson.
It is possible to become so focused on the storm that we miss the presence moving through it. I know I have. The disciples were staring directly at Jesus and still struggled to understand what they were seeing. Their problem was not a lack of information. Their problem was a failure of recognition.
Perhaps ours often is too.
Many of us spend years asking God to remove obstacles, solve problems, and provide certainty. Yet some of the most significant moments in Scripture occur not when circumstances change, but when people suddenly recognise who has been present all along.
Moses at the burning bush.
Jacob wrestling through the night.
Elijah on the mountain.
The disciples on the lake.
Again and again, the revelation comes before the resolution.
The Hidden Detail Changes Everything
The hidden detail in this story is not that Jesus walked on water. Most readers already know that.
The hidden detail is that Jesus intended to pass by.
Once we understand what that phrase meant within Israel’s Scriptures, the entire story changes. What initially looked like a miracle becomes a revelation. What seemed to be about power becomes a story about identity.
The storm matters. The water matters. The miracle matters. Yet none of those things is the centre of the story.
The centre of the story is Jesus.
The disciples think they are witnessing an extraordinary act. Mark wants them, and us, to recognise something far greater.
Ultimately, the question is not how Jesus walked on water, or even whether he can calm the storms of our lives.
The question is whether we can recognise him when he appears within them.
Because once we do, everything changes.
