A River to Swim In

Anyone who has waded into a cold lake knows the body's arithmetic — ankles first, a stop, then the slow nerve to go past the knees. Ezekiel is made to wade exactly like that, except the water he steps into should not exist. A man with a measuring line leads the exiled prophet back toward the temple, where a thread of water is slipping out from under the threshold and running east, toward the desert and the Dead Sea. The man measures off a thousand cubits and walks him in: ankle-deep. Another thousand: the knees. Another: the waist. A fourth measure, and the water has risen past what he can wade — too deep now to cross, a river he could only swim in (Ezekiel 47:5).

The text never troubles to explain where it's fed from — no tributary named, no rain credited, no spring pointed to beyond the threshold it slips out from under. It simply deepens as it goes, the way grace does, the way mercy so often turns out deeper than the place we first waded in. And the deeper it runs, the more it heals.

For the river pours down into the lowest, saltiest water on earth, the sea where nothing lives, so that "the waters of the sea may become fresh" (Ezekiel 47:8). "Wherever the river goes," the prophet is told, "every living creature that swarms will live" (Ezekiel 47:9). He watches fishermen take their stand on a shore that has never held a fish, nets drying from En-gedi to En-eglaim. On both banks stand trees that do not keep the seasons: "Their leaves will not wither, nor their fruit fail... their fruit will be for food, and their leaves for healing" (Ezekiel 47:12). A dead sea, teeming — not a stream that keeps clear of the dead places, but one that runs straight into them.

We assume we must bring ourselves up to God — clean at the edge, dry and presentable, before we are fit to wade in. But the kingdom this river belongs to has never worked that way. Tim Keller, preaching through Luke's beatitudes and woes, called it an upside-down kingdom, one that reverses the world's whole scoreboard and blesses the poor and thirsty rather than the full and self-sufficient — grace that dislodges our confidence in anything we bring to the water.[1] And preaching through Luke's parables of grace, he called it an inside-out kingdom, because it does not wait for our behavior to improve before it reaches us; it changes the heart first, and the change in our hands and habits is only ever the overflow.[2] This river runs on exactly this upside-down, inside-out logic — reversing our sense of who is fit to come, and remaking us from the inside before it ever shows on the banks. It begins at the sanctuary and comes down to us, and it is widest and most alive precisely where the water was most dead. But a river must have a spring, and Ezekiel is careful where his begins: under the temple, out of the place where God dwells with his people. Centuries later a man stood in those temple courts and said, "Destroy this temple, and in three days I will raise it up" — and John tells us plainly, "he was speaking about the temple of his body" (John 2:19, 21).

On the last day of the feast that same man stood and cried, "If anyone thirsts, let him come to me and drink," and, "Out of his heart will flow rivers of living water" — and again John explains, "this he said about the Spirit" (John 7:37-39). The trickle under the threshold was always going to become a flood, and its source would be a body given and a side opened.

It opens again on the Bible's last page, where "the river of the water of life, bright as crystal" flows "from the throne of God and of the Lamb," lined with the tree of life, "and the leaves of the tree were for the healing of the nations" (Revelation 22:1-2) — the same trees, the same healing, now with a Lamb on the throne and no more sea at all. The river is still running, still deepening, still setting its course for the deadest water it can find. We do not have to make ourselves fresh to step into it. We only have to go down — ankles, knees, waist — until the floor drops away and there is nothing left to do but be carried.
