Not by Water Only

The priests and Levites came down from Jerusalem with a question: "Who are you?" (John 1:19). John would not answer it on their terms. He confessed, and did not deny: "I am not the Christ" (John 1:20). Are you Elijah? "I am not." Are you the Prophet? "No" (John 1:21). Pressed again — "Who are you? Give us an answer to take back to those who sent us" — he gave them a voice instead of a name: "I am the voice of one crying in the wilderness, 'Make straight the way of the Lord,' as Isaiah the prophet said" (John 1:22-23). Then the delegation reached the question that mattered: "Why then do you baptize if you are not the Christ, nor Elijah, nor the prophet?" (John 1:25).

John's answer pointed away from himself: "I baptize in water, but among you stands one whom you don't know. He is the one who comes after me, who is preferred before me, whose sandal strap I'm not worthy to loosen" (John 1:26-27). He baptized, he said, for one reason: "I didn't know him, but for this reason I came baptizing in water, that he would be revealed to Israel" (John 1:31). And the revealing came by a sign given beforehand: "On whomever you will see the Spirit descending and remaining on him is he who baptizes in the Holy Spirit" (John 1:33). The water was never the destination. The water was the road by which the One who baptizes with the Spirit would be manifested to Israel.

John's water was not new. Israel had been sprinkled for centuries. Under the law, the ashes of a slain heifer were kept as water for removing impurity; it was purification from sin, and a clean person sprinkled the unclean on the third day and on the seventh day, and the unclean one was clean by evening (Num 19:9, 19). Note what the pattern already held: the cleansing water carried a death in it. The heifer was slain and burned before there was water to sprinkle. Purification never floated free of sacrifice.

Then God promised to take the sprinkling into His own hand. "I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your filthiness and from all your idols" (Ezek 36:25). He did not stop at washing: "I will also give you a new heart, and I will put a new spirit within you. I will take away the stony heart out of your flesh, and give you a heart of flesh. I will put my Spirit within you, and cause you to walk in my statutes" (Ezek 36:26-27). Sprinkle, cleanse, replace, indwell, cause — every verb has God as its subject. The Servant would extend that sprinkling beyond Israel: exalted and lifted up, "He will sprinkle many nations," and kings would shut their mouths at what they had not been told (Isa 52:13, 15). A fountain would be opened "for sin and for impurity" (Zech 13:1). Water would be poured on the thirsty ground, and God's Spirit on Israel's offspring (Isa 44:3). The messenger would prepare the way, but the Lord Himself would come to His temple as refiner and purifier, refining the sons of Levi until their offerings stood in righteousness (Mal 3:1-3) — and Elijah would be sent before the great and awesome day (Mal 4:5). So when the delegation asked why John baptized, the Scriptures they carried already contained the answer. A washing was coming that God would perform Himself, and the herald's water stood at its threshold.

John said as much. "As for me, I baptize you with water for repentance, but He who is coming after me is mightier than I… He will baptize you with the Holy Spirit and fire" (Matt 3:11). And the Lord stated the new birth in Ezekiel's own terms: "Most certainly I tell you, unless one is born of water and Spirit, he can't enter into God's Kingdom" (John 3:5). Water and Spirit are not two births. They are one cleansing act of God, promised in Ezekiel and named by Christ. That is why the rebuke follows immediately: "Are you the teacher of Israel and do not understand these things?" (John 3:10). Nicodemus owned the text. The text was the explanation.

Yet water alone is not the whole testimony, and the same apostle who recorded the baptism guarded the point decades later: "This is he who came by water and blood, Jesus Christ; not with the water only, but with the water and the blood. It is the Spirit who testifies, because the Spirit is the truth. For there are three who testify: the Spirit, the water, and the blood; and the three agree as one" (1 John 5:6-8). Water names the baptism, where the Spirit descended and remained and the Son stood revealed. Blood names the cross, where the Son was slain. A Christ of water only would be a manifested Christ who never died — an anointed example, a cleansed teacher, a king without a cross. John refuses him. The One revealed at the Jordan is the One who bled at Golgotha, and the apostle's testimony holds the two in one coming.

The blood was never missing from John's witness; it stood inside the baptism chapter itself. Between John's answer to the delegation and his confession of not knowing, the Gospel places the next day's cry: "Behold, the Lamb of God, who takes away the sin of the world!" (John 1:29). Lamb is blood language. The herald announced the water and the Lamb in the same place, in the same week, to the same crowds. And at the end, both issued from one body: a soldier pierced His side, and blood and water came out (John 19:34). The eyewitness pressed his testimony there too — the one who saw it has testified, and his testimony is true, so that we also may believe (John 19:35). First John 5 is that same witness, still testifying, now in a letter.

The frame is a courtroom, and John says so. "If we receive the witness of men, the witness of God is greater; for this is God's testimony which he has testified concerning his Son" (1 John 5:9). The content of the testimony is not information about life; it is life itself, located in a Person: "The testimony is this: that God gave to us eternal life, and this life is in his Son. He who has the Son has the life" (1 John 5:11-12). Faith, then, does not rest on water as evidence, nor on blood as evidence. Faith rests on the God who testifies through Spirit, water, and blood, and whose three witnesses agree as one. The believer carries that testimony within (1 John 5:10).

Behind all of this stands the rock in the wilderness. Paul names it without hesitation: Israel "all drank the same spiritual drink. For they drank of a spiritual rock that followed them, and the rock was Christ" (1 Cor 10:4). At Horeb, God commanded the striking: He would stand before Moses on the rock, Moses would strike it, and water would come out for the people to drink (Ex 17:6). The Rock was struck, once, by command. Christ likewise was struck once. He appeared once for all to put away sin by the sacrifice of Himself (Heb 9:26). One sacrifice for sins forever, and then He sat down (Heb 10:12). The blood of 1 John 5 is that one striking. There is no second. Where God has given forgiveness, there remains no more offering for sin (Heb 10:18).

That is why the second rock scene reads the way it does. At Kadesh the command had changed: "Take the rod, and assemble the congregation, you, and Aaron your brother, and speak to the rock before their eyes, that it pour out its water" (Num 20:8). Speak — not strike. But Moses gathered the assembly and said, "Hear now, you rebels! Shall we bring water out of this rock for you?" and "Moses lifted up his hand, and struck the rock with his rod twice, and water came out abundantly" (Num 20:10-11). The water flowed; Israel and their livestock drank. And God judged the act in one sentence: "Because you didn't believe in me, to sanctify me in the eyes of the children of Israel, therefore you shall not bring this assembly into the land which I have given them" (Num 20:12). Psalm 106 adds the rash words spoken there (Ps 106:33). The sin was unbelief, and failure to treat God as holy — the text states its own charge. Under that charge the pattern stands: the Rock, once struck, is afterward spoken to. A second striking declares, in act, that the first was not enough.

So the posture of the new covenant toward Christ is speech, not striking. "If you knew the gift of God," He told the Samaritan woman, "you would have asked Him, and He would have given you living water" (John 4:10). After His glorification, rivers of living water would flow — the Spirit, whom those who believed were to receive (John 7:38-39). The thirsty do not raise a rod against the Rock. They come, they ask, they drink. He must increase; the herald decreases (John 3:30). The witnesses agree; the flow continues.

Moses never entered the land he viewed from the mountain (Deut 34:1-5). The man who struck the Rock twice died outside Canaan, and Joshua led Israel in. Yet on another mountain, Moses stands in glory, talking with Christ Himself (Matt 17:3) — the mediator barred from the earthly inheritance, present in the true one, beside the Rock he struck and the Lamb he foresaw. How the barred mediator stands there, Scripture shows but does not explain. The testimony is God's. The witnesses are three. And the three agree as one.
