John at the Jordan: A Familiar Act, a Radical Message


As we discovered in the previous post, when John appeared along the Jordan River, calling people to be baptized, he wasn’t inventing something new. Ritual washing was already woven into Jewish life. From the Temple mikva’ot in Jerusalem to the purifying baths found in nearly every Galilean village, immersions were familiar acts of cleansing – acts that symbolized a person’s desire to approach God with purity.

But John’s baptism was different. He took a familiar ritual and reoriented it – not around the Temple, not under priestly oversight, but around a message: “Repent, for the kingdom of heaven has come near” (Matthew 3:2). What had long been an act of purification became a call to transformation.

A Baptism Outside the System

In the first century, ritual washings were part of the rhythm of faith. These washings – tevilah in Hebrew – were repeated again and again as needed. They prepared one externally for worship, but didn’t change the heart.

John’s setting was the first sign that something new was happening. He wasn’t at the Temple. He wasn’t officiating under the watchful eye of priests. He was out in the wilderness – at the Jordan, the river that once marked Israel’s entry into the Promised Land. There, at the symbolic border of new beginnings, he called people not to repeat a ritual, but to prepare for a divine encounter.

“Repent, for the kingdom of heaven is at hand!” — Pieter de Grebber, “St. John the Baptist Preaching Before Herod,” 17th century )

Repentance: More Than Regret

John’s call was simple yet seismic: “Repent.” The Greek word metanoia literally means “to change one’s mind,” but it carries far more than intellectual reconsideration. In Hebrew thought, repentance – teshuvah – means turning around.

There is an order to repentance. Before one can turn around and change direction, they must first come to a realization that they might, in fact, be going the wrong way – a change of mind.. What did the people have to change their minds about? About God? About His nature? About their role as God’s kingdom people? About justice and mercy?

Turns out, the first-century Jewish people had a lot to change their minds about. Likely that’s why John (and later, Jesus) called the religious leaders a brood of vipers (Matthew 3:7, Matthew 12:34). The religious leaders (priests, Pharisees, Sadducees, zealots, etc.) were actually leading people away from God by misrepresenting his character, relying on their own national ideologies.

John’s message of repentance wasn’t merely to feel sorry or guilty. It meant rethinking about God, His character, and especially the nature of His kingdom…

…because it was breaking in!

Preparing the Way

John’s ministry echoed the words of Isaiah:

“A voice of one calling in the wilderness, ‘Prepare the way for the Lord, make straight paths for him’” (Isaiah 40:3).

To “prepare the way” meant to ready the heart for God’s arrival. Just as ancient workers leveled roads for a coming king, John’s preaching cleared the inner landscape – removing obstacles of pride, hypocrisy, and indifference.

His baptism was a symbol of readiness. Those stepping into the Jordan weren’t simply washing away ritual impurity; they were acknowledging their need for renewal and pledging themselves to hear a new narrative.

This is why tax collectors and soldiers came, confessing their sins (Luke 3:10–14). It’s why Pharisees, used to controlling religious access, bristled at John’s independent authority (Matthew 3:7–9). John’s message cut through social boundaries and religious assumptions. He was leveling the ground for the coming King.

The Wilderness as God’s Classroom

I suspect the wilderness wasn’t accidental. Throughout Israel’s story, God met His people in desolate places – calling them out of comfort to confront their need. From Moses’ encounter at the burning bush to Israel’s forty years of wandering, the wilderness was where God stripped away illusion and invited trust. 1

By situating his baptism there, John was signaling a return to dependence on God. The wilderness was a place of renewal and recalibration – a spiritual reset for those willing to leave old thinking behind.

And the Jordan itself carried deep memory. This was the river Joshua crossed when Israel finally entered the land of promise (Joshua 3). To stand in those waters again was to reenact a moment of covenant renewal – to step forward in faith toward God’s future.

A Radical Message in Familiar Waters

So when John called Israel to the Jordan, he wasn’t rejecting tradition – he was fulfilling it. He transformed an external practice into an internal awakening, a ceremonial act into an ethical summons, and a repeated ritual into a watershed moment.

John’s baptism didn’t cleanse in order to make one fit for Temple sacrifice; it cleansed to make one ready to meet the Lamb of God who would take away the sin of the world (John 1:29).

And that was radical.

The Heart of the Matter

Repentance, then, was not a demand to do better but an invitation to be changed. It was not a self-improvement program but a surrender to God’s transformative work.

The act of entering the water symbolized death to the old self and emergence into new life. It prefigured the deeper baptism Jesus would later offer – baptism with the Holy Spirit (Mark 1:8), an inner renewal only God could accomplish.

John’s message pressed toward that truth. “I baptize you with water for repentance,” he said, “but after me comes one who is more powerful than I… He will baptize you with the Holy Spirit and fire” (Matthew 3:11).

The familiar act pointed beyond itself – to a greater cleansing, a truer renewal, a living relationship with the King Himself.

A Call That Still Echoes

John’s voice still echoes across the centuries. In a world that often substitutes religious performance for heart change, his message calls us back to the Jordan – to the place of turning, of release, of preparation.

Repentance remains the doorway to encounter. It is the act of aligning our hearts with God’s kingdom and making room for His reign.

John the Baptist Didn’t Invent Baptism


Before John the Baptist ever called people to the Jordan, the Jewish world already knew something of water and washing. Immersion wasn’t a novelty. It was woven into daily life, into rhythms of purity, preparation, and belonging. John didn’t invent the idea — he simply took it out of the Temple courts and into the wilderness.

The Mikveh: Ritual Purity and Readiness

The Hebrew word mikveh means “a gathering” — often of water — and it came to describe a pool used for ritual immersion. These baths, carved into stone and fed by “living” water (rain or spring), appear throughout first-century Israel. Archaeologists have uncovered mikva’ot (plural) near the Temple Mount, around Qumran, and in Galilean villages — evidence of how normal immersion had become by the time of Jesus.

In Jewish life, immersion in the mikveh wasn’t about moral guilt but ritual status. It restored purity so one could reenter worship or communal life after contact with impurity — things like childbirth, disease, or death (see Leviticus 15; Numbers 19). Priests immersed before serving; ordinary people did so before festivals or Sabbath meals. It was familiar, repeatable, expected.

In other words, the mikveh wasn’t about forgiveness. It was about fitness — being fit to approach God’s presence.

Proselyte Immersion: From Outsider to Insider

By the first century, another form of immersion had emerged: that of Gentiles converting to Judaism. A convert underwent three steps — circumcision (for men), immersion, and a temple sacrifice. The immersion symbolized a transition from impurity to purity, from outsider to member of God’s covenant people.

Rabbinic writings later summarized, “By three things did Israel enter into the Covenant — by circumcision, immersion, and sacrifice.” The convert, it was said, became “like a newborn child.” It was a fresh start — but again, a ceremonial one.

Prophets, Purity, and the Promise of Cleansing

Long before mikva’ot were carved in stone, the prophets had used washing language symbolically:

“Wash yourselves; make yourselves clean,” Isaiah pleaded (1:16). “I will sprinkle clean water on you,” promised Ezekiel, “and you shall be clean … I will give you a new heart and put a new spirit within you” (36:25–27).

Water had always hinted at something deeper — not just the washing away of dust, but the cleansing of the heart.

Groups like the Essenes took this seriously. The Dead Sea Scrolls describe daily immersions tied to covenant faithfulness and inner purity. For them, water symbolized moral renewal — a visible act expressing invisible obedience.

A Familiar Form, a Coming Shift

So when John began calling Israel to the Jordan, he wasn’t performing a strange ritual. He was using a symbol everyone already understood. Immersion was a language his hearers spoke fluently.

What was new was the location — outside the Temple system — and the message behind it. But we’re not there yet. For now, it’s enough to see that John’s work grew out of a long Jewish conversation about cleansing, belonging, and readiness before God.

In an earlier post, Baptism, Pickles, and Steel Poles, we compared baptism to both the preserving of cucumbers and the strengthening of steel. Ordinary materials — transformed by immersion. That’s what was happening in Israel’s ritual life long before John: familiar practices pointing toward deeper transformation.

John didn’t invent baptism; he reinterpreted it. He stood in a long tradition of washing and readiness — but instead of pointing people to the Temple, he pointed them toward repentance and the coming King (and His kingdom).

Before the new could begin, the old had to be remembered. And the old, as it turns out, had always been whispering: “Get ready.”
