31 May 2026 • The Feast of the Holy Trinity • John 3:1–15
Most assuredly, I say to you, We speak what We know and testify what We have seen, and you do not receive Our witness. If I have told you earthly things and you do not believe, how will you believe if I tell you heavenly things? (Jn 3:11–12).
This is the Word of the Lord that came to me, so that you may believe that Jesus is the Christ, the Son of God, and that by believing, you may have life in His + Name. AMEN.
Nicodemus opens with a compliment, but it is already the wrong move. “Rabbi, we know that you are a teacher come from God.” He has come in the dark to a teacher he hopes to understand, and his very first word is we know — he arrives with preexisting knowledge and intends to add this Galilean to it. And Jesus declines the compliment entirely. He says nothing about teaching and nothing about knowing. He says that unless a man is born from above (anothen), he cannot so much as see the kingdom of God — and no one, however learned, was ever present at his own birth, or arranged it, or understood it while it was happening to him.
So, of course, the next words are a stumble. “How can a man be born when he is old? Can he enter a second time into his mother’s womb?” Nicodemus hears “born again” and, as we all do, reaches for something he might do on his own — climb back into a beginning he could manage on his own terms, take the second birth into his own hands the way he has taken everything else. He cannot imagine a birth that is not, at least in part, his own achievement. And that misunderstanding is the whole conversation. He keeps trying to make the new birth into a work, and it will not become one.
Then Jesus shuts up every clever person in the room. “You are the teacher of Israel, and yet you do not understand this?” It is not a sneer. It is a diagnosis. The finest mind in the nation, the man whose entire life is the labor of understanding, is told that understanding is precisely the rope that does not reach the bottom. Flesh gives birth to flesh, Jesus says — meaning your reasoning is flesh too, and flesh begets only its own kind, so the mind working at knowing produces nothing but more mind, never the new thing, never life. The wind blows where it wishes; you hear the sound of it and cannot tell where it comes from or where it is going. You may as well command the weather as command the Spirit to be born in you.
“How can these things be?” And the question simply hangs there in the dark. What is remarkable is that Jesus never answers the how. He answers a different word. He answers where. “No one has ascended into heaven except the one who came down from heaven.” Hear what that does to the man leaning forward to comprehend the things of God. Every upward inch of effort, the whole project of climbing toward heaven by knowing — no one has made that climb. No one. The road that Nicodemus has spent his life walking has no traffic going up. All the traffic on it comes down. He bent his mind toward heaven, and heaven had already bent down to him, sitting across from him in the lamplight, in the flesh, calling him by his trouble.
And then one of the oldest pictures in Israel’s memory, given in the middle of the night. “As Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up.” A whole camp was dying of snakebite, the venom already in the blood, and the cure was not to study the bite, master the poison, or understand a single thing about it. The cure was a bronze serpent raised on a pole and one instruction: Look at it and live. The dying did not heal themselves. They turned their eyes to the thing God had lifted up, and the lifting up was the healing, and they lived. So now the Son of Man — to be lifted on a cross that this same Nicodemus will one day help to lower, his arms under the dead weight of God — is lifted up so that everyone bitten, which is everyone, and dying, which is everyone, has only to look and not perish.
You look, and you live. You do not first understand, and then live. The teacher came carrying everything he knew and was handed two things he could do nothing with: a birth he could not perform and a cross he could only behold. And even the looking is not the last small work left to his credit — the eyes that turn to the lifted Son are opened by the same Spirit who blows where He wills, the birth of water and the Spirit, not of the will of the flesh, not of any man’s deciding. It is given the whole way down.
Now, notice that the direction has not changed in two thousand years. You did not climb here this morning. You were called, summoned out of bed by a bell and a habit you did not invent, and everything that happens in this room moves the one way the whole conversation with Nicodemus moved — downward, from God to you, never the reverse. We have a bad instinct that calls this hour our offering to God, our ascent, our reaching up. It is the opposite. It is God’s service to us. The God no bell can sound comes down the only road that has ever had traffic on it, and He comes down in things you can hear and feel and swallow, because He has decided that faith will always have something outward to take hold of, something your senses can carry into your heart.
He comes down first at the font. The new birth Nicodemus could not perform for himself is performed, in front of you, on an infant, or adolescent, or adult who can perform nothing at all — who cannot decide, cannot understand, cannot contribute so much as a nod, and is sunk under the water and drawn up out of it anyway. There is the whole sermon in a basin of water: the old man held under until he drowns, the new man lifted out, and the one being born adding exactly nothing, which is precisely what Jesus told the teacher in the dark. It is plain water, except that it is bound to the Word and the Name we bless many times this day, and so it is a washing of new birth in the Holy Spirit. And it does not expire. You return to it every morning you wake and drown the old Adam again; a Christian life is just that font, opened once and never closed.
He comes down in the Word spoken at you. When the pastor says I forgive you all your sins, that is not a man reporting his good opinion of you. That is the descended Word placed into a man’s mouth so it can reach your ears, God’s own verdict coming down from outside you, where no doubt of yours can touch it and wreck it. You did not talk yourself into peace. It was handed to you.
And today, you did the thing this whole feast day is built to do. You confessed Him you cannot fathom — three persons and one God, none greater and none less, the substance undivided and the persons unconfused — and you did not understand a word of it, but you said it anyway, because confession is never the same as comprehension. Then you will sing what the burning ones sing over a throne whose bottom no creature has found: Holy, holy, holy — the threefold cry that has no bottom to it. We do not first measure God and then praise Him. We are given Him, and we sing.
Then you will come down to the rail, and the Son who was lifted up on the pole will be lifted up again in a man’s two hands, and the instruction will no longer only be look and live. It will be take, eat, and live. The very body that hung on the cross, the very blood that ran down it, comes down off the altar and into your mouth — truly there, in and under the bread and the wine, not a token of an absent Lord but the present One, given and shed for you for the forgiveness of sins. And mark how sure it is: it does not wait on your worthiness, your feelings, or your grasp of the mystery. The Word makes it His body, and so His body is what the worthy and the unworthy alike receive — the believing to their life, the scoffing to their judgment — because everything here rests on what His lips said and nothing on what yours can fathom. The dying are not shown a cure across the room and told to understand it. The cure is laid on the tongue.
So Nicodemus came in by night, a teacher with an understanding of what he knew, and went back out into the dark, a man being born — the very thing he said could not be — happening to him as he asked how. And it keeps on happening, every Lord’s Day, in a basin, a voice, and a little bread and wine, to people who bring nothing to it but the snakebite. It comes down out of the Father who so loved this dying world, through the Son lifted up and now handed over, carried by the Spirit who opens dead eyes and dead mouths to receive Him — and only afterward does any of it turn back up as praise.
We are not asked to fathom Him. We are washed, we are absolved, we are fed; and so we are kept alive by the God we will never comprehend, who keeps coming down the one road home. Amen.
In the holy Name + of Jesus. AMEN.
