What Does Genesis 13:16 Mean?

"I will make your offspring like the dust of the earth, so that if anyone could count the dust, then your offspring could be counted." The offspring promise is given a new comparison: dust. Chapter 12's "great nation" becomes here the incomprehensibly numerous as dust. The comparison is both poetic and precise: dust is what the earth itself is made of; to make Abram's offspring like dust is to associate his descendants with the substance of the creation itself. The comparison is also personal: it was from dust that Adam was made, and to dust that he would return.

The numerical comparison is set against the background of the barren Sarai. God promises offspring as numberless as dust to a man whose wife cannot conceive. This is not a proportional promise; it is an impossible promise addressed to an impossible situation. The size of the promise corresponds to the size of the obstacle: the greater the impossibility of natural fulfillment, the more clearly the fulfillment, when it comes, will be attributable to divine power rather than human fertility.

The stars comparison will come in chapter 15; the sand comparison in chapter 22. God gives the same offspring promise three times with three different comparisons, each one an image of incomprehensible number. Together they form a cumulative portrait of an inheritance that no individual census can capture. The Apostle Paul understood this promise as fulfilled not only in the physical descendants of Abraham but in all who share his faith: the offspring like the dust of the earth includes all who believe as Abraham believed, from every nation and tongue.
