A Door in the Side: The Story Behind the Song
Part One: For the Newcomer
One picture, told six times
This song doesn't tell one story. It tells six short ones, and they're all the same story.
Each verse is a scene from somewhere in the Bible: a garden, a flood, a desert, a prophet's vision, a cross, a tomb. In every one of them, something is opened in the side, and life comes out of it. The chorus keeps returning to that picture: a door in the side.
You don't need to know the Bible to enjoy the song. But if you'd like to know what's going on underneath it, here's each scene in plain words.
The gardener's sleep
The Bible begins in a garden. God makes the first man, Adam, and puts him there to tend it. Adam is the first gardener.
But Adam is alone, and God says that isn't good. So God puts Adam into a deep sleep, opens his side, and from it makes the first woman, Eve. When Adam wakes and sees her, he says she is "bone of my bones, and flesh of my flesh."
Hold on to that picture: a man asleep, his side opened, and a bride coming out of it. Everything else in the song comes back to it.
The door in the ark
Later, the world grows so violent that God sends a flood. He tells Noah to build a great wooden boat, the ark, and to seal it inside and out. The ark has one door, and God tells Noah to put it in the side.
When everyone is inside, the Bible says something easy to miss: the Lord shut the door. Noah didn't close himself in. God did. Everyone who was saved was saved by going in through one door in the side, and being shut in by God.
The rock in the desert
Centuries later, God's people are wandering in the desert, dying of thirst. God tells Moses to strike a rock with his staff, and God says He will be standing there on the rock. Moses strikes it, the rock splits, and water pours out, enough for everyone.
The New Testament tells us what that rock meant: "that Rock was Christ." Later still, when Moses asks to see God's glory, God hides him in a cleft, a split in a rock, and covers him with His hand while His glory passes by. The safest place in the world turns out to be inside a split rock.
The river from the temple
The prophet Ezekiel has a vision of God's temple, and he sees water trickling out from its side. He follows it, and it gets deeper: up to his ankles, then his knees, then his waist, until it's a river too deep to cross. Wherever that river flows, dead things come back to life.
Jesus later uses this picture of rivers of living water to describe the Holy Spirit, given to everyone who comes to Him.
The spear
Now the song arrives at the center of it all. Jesus is crucified. To speed up the deaths, the soldiers break the legs of the men on the crosses, but when they come to Jesus, He's already dead, so they don't break His bones. Instead, one soldier pushes a spear into His side, and blood and water pour out.
Now look back at the first verse. God opened the side of the sleeping Adam, and a bride came out. Here, the side of Christ is opened as He sleeps in death, and out comes blood and water, and from His death comes His bride, the church: all the people He saves. The Bible calls the church the bride of Christ, and says Christ "loved the church, and gave himself for it."
That's why the ark's door was in the side, why the water came out of the struck rock, and why the river flowed from the side of the temple. They were all pointing here.
The gardener again
On the third day, a woman named Mary comes to Jesus's tomb, which is in a garden. She finds it empty and weeps. A man speaks to her, and she thinks He's the gardener. Then He says her name, and she realizes it's Jesus, risen from the dead.
She was more right than she knew. The Bible calls Jesus the "last Adam." The first gardener lost the first garden. This Gardener walked out of a tomb in a garden to start the whole world over.
The doubter
That night, Jesus's friends are hiding behind locked doors, and suddenly He's standing among them and shows them His hands and His side. One friend, Thomas, isn't there, and he says he won't believe unless he can put his hand into Jesus's side.
A week later, behind locked doors again, Jesus appears and says to Thomas: "Reach hither thy hand, and thrust it into my side." Thomas doesn't argue his way to faith. Jesus comes to him and offers His wound. Thomas answers, "My Lord and my God." That's where the song ends.
What it means for you
The whole Bible keeps showing the same thing: life comes through an opened side. The ark had one door, and Jesus says, "I am the door: by me if any man enter in, he shall be saved." The wound in His side is that door.
You don't build the door, and you don't open it. God built it, and Christ was opened for it. The song's chorus ends with an invitation, and it's the Bible's own last invitation: "The Spirit and the bride say, Come."
Come in, through the door in the side.
Part Two: For the Theologian
The governing text: Genesis 2:21–24
The song's interpretive center is Genesis 2, and three Hebrew terms carry its weight.
The first is tardēmâh (2:21), the "deep sleep" that the LORD causes to fall on Adam. It is not ordinary sleep but a divinely imposed suspension of human agency. The same word falls on Abram in Genesis 15:12, where God alone passes between the divided animals and ratifies the covenant unilaterally while the human party lies inert; it falls on Saul's camp as "a deep sleep from the LORD" (1 Samuel 26:12). In both Genesis texts, God acts constitutively while man contributes nothing. The bride, like the covenant, is pure gift. The song's "the kind that only God can keep" compresses this.
The second is ṣēlāʿ (2:21–22), traditionally "rib." Outside Genesis 2, the word never denotes an anatomical rib. It means side: of a hill (2 Samuel 16:13), but overwhelmingly in architectural contexts, the sides of the ark of the covenant (Exodus 25:12, 14), the side-boards of the tabernacle (26:20, 26–27), and the side-chambers of Solomon's temple (1 Kings 6:5, 8) and of Ezekiel's visionary temple (Ezekiel 41:5–11). The woman is drawn from a "side" in the vocabulary of sanctuary construction.
The third is the verb. The KJV text has "made he a woman," but its margin rightly gives the Hebrew wayyiben, "builded." Bānâh is the ordinary verb for constructing houses, cities, altars and the temple. God does not form the woman as He formed the man from dust (2:7, yāṣar, the potter's verb); He builds her, from a side, as one builds a sanctuary.
Combined, the lexical field is striking: under a God-imposed sleep, from a sanctuary-side, a dwelling is built. This coheres with the widely argued reading of Eden as the archetypal sanctuary. Adam's commission to "dress and keep" the garden (2:15) uses the paired verbs later assigned to the Levites' tabernacle service (Numbers 3:7–8, 8:26). The eastward entrance guarded by cherubim (Genesis 3:24) anticipates the cherubim woven into the veil (Exodus 26:31). Meredith Kline (Kingdom Prologue) and G. K. Beale (The Temple and the Church's Mission) develop the Eden–temple correspondence at length from within the Reformed tradition.
Paul supplies the license to read the scene christologically. Adam is "the figure of him that was to come" (Romans 5:14), and Christ is "the last Adam" (1 Corinthians 15:45). In Ephesians 5:30–32 he quotes Genesis 2:24 and declares, "This is a great mystery: but I speak concerning Christ and the church." The KJV's "of his flesh, and of his bones" in 5:30, absent from the Alexandrian witnesses but present in the Byzantine tradition, makes the echo of Genesis 2:23 explicit; even without it, the quotation in 5:31 secures the connection.
The ark: a covering and a door
Genesis 6:14 instructs Noah to "pitch it within and without with pitch": wəkhāpartā … bakkōpher. This is the only place in the Old Testament where the verb kāphar means "to coat with pitch." Elsewhere the root is the vocabulary of atonement (kippār, kippurîm, Leviticus 16), and the noun kōpher elsewhere means "ransom" (Exodus 30:12, Psalm 49:7). The lexical overlap is real, but the theologian should resist the root fallacy: shared consonants do not prove shared meaning, and James Barr's warnings apply. The song therefore uses the resonance only as image ("with covering laid"), not as an argument. What is exegetically secure is the ark's function as a figure of salvation through judgment (1 Peter 3:20–21, Hebrews 11:7).
The door is set "in the side thereof" (6:16), using ṣaḏ, a different word from ṣēlāʿ, so the link to Genesis 2 is conceptual rather than lexical. Its Christological reading is ancient: Augustine treats the side-door as a figure of the wound in Christ's side, through which those who come to Him enter (City of God 15.26). The text's most theologically weighty detail is 7:16: "and the LORD shut him in." Noah enters; God closes. The door is God's to open and God's to shut (compare Revelation 3:7).
The rock: God beneath the rod
In Exodus 17:5–6, Moses is to strike the rock at Horeb with "thy rod, wherewith thou smotest the river," the rod of judgment on Egypt. God adds: "Behold, I will stand before thee there upon the rock in Horeb." The rod of judgment descends on the place where God has said He is standing, and life-giving water comes out of it. Paul's commentary is unambiguous: they "drank of that spiritual Rock that followed them: and that Rock was Christ" (1 Corinthians 10:4). The smitten Rock anticipates the Servant "smitten of God, and afflicted" (Isaiah 53:4).
The typology is sharpened by Numbers 20, where Moses is commanded to speak to the rock and instead strikes it twice, forfeiting entry into Canaan. The rock was to be struck once; thereafter, it was to be addressed. Christ was "once offered" (Hebrews 9:28) and is now approached by word and prayer.
The song's "in that cleft God hid the man" draws on Exodus 33:22, where God sets Moses "in a clift of the rock" and covers him with His hand as His glory passes. Precision requires a note: the Exodus 33 cleft is not textually identified with the Horeb rock of chapter 17, though both are at the mountain of God. The lyric joins them as one image of refuge in a riven rock, the image the church has long sung ("Rock of Ages, cleft for me").
The waters: from the temple's side
Ezekiel 47:1 describes waters issuing "from under the threshold of the house eastward … from the right side of the house, at the south side of the altar." They deepen from ankle to knee to loins to an impassable river (47:3–5), and "every thing shall live whither the river cometh" (47:9). The vision belongs to a canonical sequence: "living waters shall go out from Jerusalem" (Zechariah 14:8); "a fountain shall come forth of the house of the LORD" (Joel 3:18); and finally "a pure river of water of life … proceeding out of the throne of God and of the Lamb" (Revelation 22:1).
The hinge is John 7:37–39. On the last day of Tabernacles, the feast whose water-drawing ceremony (described in Mishnah Sukkah 4:9) enacted these prophecies, Jesus cries, "He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water," and John glosses it as the Spirit, not yet given "because that Jesus was not yet glorified." Whether "his belly" refers to the believer or to Christ depends on punctuation and is disputed; the second reading, which makes Christ the source, aligns with John 19:34 and with the temple Christology of John 2:19–21, where Jesus calls His body the temple. On either reading, the Spirit flows only after the glorification, which in John is the cross.
The spear: John 19:31–37
The soldiers break the legs of the two others but, finding Jesus already dead, do not break His. One soldier pierces His side, "and forthwith came there out blood and water." John adds an unusually emphatic eyewitness attestation (19:35) and two fulfillments: "A bone of him shall not be broken" (Exodus 12:46, Numbers 9:12, with Psalm 34:20 in view) and "They shall look on him whom they pierced" (Zechariah 12:10). The next verse of Zechariah reads: "In that day there shall be a fountain opened to the house of David … for sin and for uncleanness" (13:1). The pierced one and the opened fountain are canonically adjacent.
The Greek verb is enyxen, "pierced" or "pricked." The Vulgate rendered it aperuit, "opened," and Augustine built on that word: the evangelist chose it so that "there, in a manner, the door of life might be thrown open" (Tractates on John 120.2), explicitly linking the wound to the ark's door. Chrysostom draws the Adam parallel directly: as Eve was formed from the side of the sleeping Adam, so the church from the side of Christ. The song's mirrored line, "He opened up the Sleeper's side," stands in this tradition, and the theologian should note that it depends on the Latin, not the Greek.
The patristic tradition commonly read the blood and water as the sacraments of the Supper and baptism. Calvin, commenting on the passage, connects them instead to the realities the Old Testament rites foreshadowed: the blood to atonement, the water to washing, both fulfilled in Christ, with the sacraments as signs of those realities rather than their source. The Reformed position thus affirms that the church is born from Christ's death (Acts 20:28, "purchased with his own blood"; Ephesians 5:25–27, cleansed "with the washing of water by the word") while declining any ecclesiology in which the church, because it came from His side, shares in His mediation. The church is the fruit of the wound, not its co-agent. The song's "out came water, blood, a bride" asserts the first and nothing of the second.
The garden and the gardener
John alone notes that the crucifixion site had a garden (kēpos) and that the new tomb lay within it (19:41). Mary "supposing him to be the gardener (kēpouros)" (20:15) is often read as dramatic irony. John's Gospel invites more: it opens with "In the beginning" (1:1, echoing Genesis 1:1), places the resurrection on "the first day of the week" (20:1), and has the risen Christ breathe on the disciples (20:22) with the verb the Greek Old Testament uses for God breathing into Adam (Genesis 2:7). Read with Paul's "last Adam" (1 Corinthians 15:45), the lyric "And so He was" is a theological claim the text's patterning supports, though John does not state it.
The shut doors and the opened side
The risen Christ comes twice through shut doors (John 20:19, 26) and both times displays His side (20:20, 27). He had already said, "I am the door: by me if any man enter in, he shall be saved" (10:9). Hebrews names the entry explicitly: "a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh" (10:20), the veil having been torn at His death (Mark 15:38). The way east of Eden, closed and guarded (Genesis 3:24), is reopened through the flesh of the Last Adam.
Thomas sets terms for belief: "Except I … thrust my hand into his side, I will not believe" (20:25). Christ meets those terms on His own initiative: "Reach hither thy hand, and thrust it into my side" (20:27). Faith is called forth by Christ's self-presentation, not achieved by Thomas's inquiry, and the confession "My Lord and my God" is the climax of the Fourth Gospel's Christology, followed directly by its purpose statement (20:31).
The bride as city and temple
Revelation closes the loop. The bride, the Lamb's wife, is shown to John as the holy city (21:2, 9–10), which has no temple "for the Lord God Almighty and the Lamb are the temple of it" (21:22), and from whose throne flows the river of life (22:1). Bride, city, temple, river and garden (the tree of life, 22:2) converge. The ṣēlāʿ of Genesis 2 has become a dwelling in the fullest sense: "the tabernacle of God is with men" (21:3). The canon's last invitation, "the Spirit and the bride say, Come" (22:17), is the song's chorus.
Hermeneutical accounting
The Westminster Confession holds that Scripture has one true and full sense and that the infallible rule of interpretation is Scripture itself (WCF 1.9). Typology, rightly practiced, is not a second sense but the recognition of patterns God built into redemptive history and made explicit in their fulfillment. Honesty requires distinguishing three levels of warrant in the song:
- Explicit in the New Testament: Adam as type of Christ (Romans 5:14), Genesis 2:24 as the mystery of Christ and the church (Ephesians 5:32), the rock as Christ (1 Corinthians 10:4), the unbroken bone and the pierced one (John 19:36–37), the flood as a figure of salvation (1 Peter 3:20–21), and the bride as the city (Revelation 21).
- Warranted by canonical patterning: the Eden–temple correspondence, Ezekiel's river as the Spirit flowing from Christ (John 7:37–39 with 2:21 and 19:34), the Zechariah 12–13 sequence, and the gardener irony read with John's new-creation framing.
- Traditional and suggestive: the ark's side-door as Christ's wound (Augustine), the "opened" side (dependent on the Vulgate), and the kōpher resonance (lexical, not semantic).
The song places the third tier only in its imagery, never in its doctrinal claims.
Doctrinal summary
The song's theology is Reformed at every joint. The bride comes from a sleeping man who contributes nothing (Genesis 2:21), as the covenant is ratified while Abram sleeps (15:12); God shuts the ark (7:16); God stands where the rod falls (Exodus 17:6); Christ comes through shut doors to the doubter (John 20:26). Salvation is the work of God alone: effectual calling by His Spirit, man being "altogether passive therein" until quickened (WCF 10.1–2). Christ "purchased not only reconciliation, but an everlasting inheritance" for those given Him (WCF 8.5), and the church thus purchased is "the spouse, the body, the fulness of him that filleth all in all" (WCF 25.1). And the chorus's "Come in" is the free and sincere offer of the gospel, which the Canons of Dort require be declared "promiscuously and without distinction" to all (II.5), even as the door through which they come was built, opened and kept by God alone.
