All the Families of the Earth

Genesis 12 opens on the far side of a disaster. One chapter earlier the whole earth had “one language and the same words,” and the people of Shinar said to one another, “Come, let us build ourselves a city and a tower with its top in the heavens, and let us make a name for ourselves, lest we be dispersed over the face of the whole earth” (Genesis 11:4). They got the dispersal they feared. And the passage that follows the scattering is a genealogy — name after name, generation after generation, narrowing down through Shem to a man named Terah — until the narrator stops the list cold with one flat sentence: “Now Sarai was barren; she had no child” (Genesis 11:30). A world scattered; a family with no future. That is the room into which God speaks.

What he says is not a rebuke. “Now the LORD said to Abram, ‘Go from your country and your kindred and your father’s house to the land that I will show you’” (Genesis 12:1). The command comes in three widening cuts — country, kindred, father’s house — each one nearer the bone, because in that world a man’s father’s house was his name, his inheritance, his insurance, and his gods all at once. Abram is asked to leave every bit of it for a destination God declines to name in advance. And we should be clear about who is being called here: Joshua would later remind Israel that “your fathers lived beyond the Euphrates… and they served other gods” (Joshua 24:2). Abram was not chosen because he had been searching for the true God. He was worshiping the wrong ones when the true God found him — which is how grace always works, arriving before we have done anything to deserve its arrival.

Then come the promises, and the word that carries them is bless — Hebrew barak, which is never merely a warm wish; it is God’s own favor set loose on a life and made effective, a word that does something to the person it lands on. The root sounds again and again across these three verses, gathering force, until it breaks its banks in the last line: “and in you all the families of the earth shall be blessed” (Genesis 12:3). That word families — mishpachot, clans — reaches back deliberately to Genesis 10, the table of the nations that had just been scattered from Babel. The promise is not that one nation will do well. It is that the scattering itself will be undone, and undone through one childless couple walking out of Haran.

There is a real claim on us in this, though it is easy to bend it into a slogan — blessed to be a blessing — as if we were the subject of the sentence and the nations were our project. The grammar runs the other way. Abram receives before he does anything; the blessing is placed in his hands before he takes a single step, and everything he becomes for the nations flows out of what was given to him first. Keller reads Genesis 11 and 12 as two rival ways of getting a name: Babel builds one, and Abram is given one.¹ We are still building towers — a career, a reputation, a portfolio, a family we can point to — and the call of God walks onto that construction site and simply offers us what we have been trying to manufacture. Let us stop building for a name and receive one. Abram’s whole answer is recorded a few chapters on in one of the plainest sentences in Scripture: “And he believed the LORD, and he counted it to him as righteousness” (Genesis 15:6). The Hebrew root under that “believed” is the one that gives us emunah — not a leap in the dark, but the steady leaning of the whole weight of a life on someone who will hold it. And he went, as the ache for a home we have never seen always sends people out, “looking forward to the city that has foundations, whose designer and builder is God” (Hebrews 11:10).

But how does a blessing actually pass from one man in a tent to “all the families of the earth”? Paul answers with startling directness: “And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying, ‘In you shall all the nations be blessed’” (Galatians 3:8). Paul is saying that Genesis 12:3 is the gospel — announced two thousand years early, in the desert, to a man with no children. And he tells us where to look for the one through whom the blessing travels: “Now the promises were made to Abraham and to his offspring. It does not say, ‘And to offsprings,’ referring to many, but referring to one, ‘And to your offspring,’ who is Christ” (Galatians 3:16). The line that runs from Abram narrows for two millennia — Isaac, Jacob, Judah, David — and comes to a single point in a manger, and then widens again to take in the world.

Notice that Genesis 12:3 sets two words side by side, blessing and curse, and holds them there unresolved. The cross is where they change places. “Christ redeemed us from the curse of the law by becoming a curse for us — for it is written, ‘Cursed is everyone who is hanged on a tree’ — so that in Christ Jesus the blessing of Abraham might come to the Gentiles” (Galatians 3:13–14). The blessing could reach the families of the earth by one road only: a man hung on a tree, under the curse we had earned, so that what was promised to Abram could be handed to strangers. Yesterday we listened to Peter standing in a Roman officer’s house saying that they “put him to death by hanging him on a tree” and that God shows no partiality (Acts 10:34, 39); this promise to Abram is the older word standing behind that sermon. And the God who asked Abram for his son on Moriah (Genesis 22:2) is the God who “did not spare his own Son but gave him up for us all” (Romans 8:32). Three chapters after the call, God would guarantee the whole thing by passing alone between the pieces (Genesis 15:17) — swearing, in effect, that if the covenant failed, he would bear the cost himself. At Golgotha he paid what he swore.

So the last page of the Bible answers the first promise made to Abram, almost word for word. John sees “a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb” (Revelation 7:9) — every family in the table of nations, the whole scattered census of Babel, gathered in and standing together at the feast on the mountain. We were among the families God had in view when he spoke in Haran. The promise was old before we were born, it was secured at a cost we did not pay, and it has arrived. That is grace, reaching down a corridor of four thousand years to find us.
