If the blessing of physical sons and daughters is not itself the greatest blessing, then it’s also the case that physical children are not the only—or even the greatest—kind of children we can have. Men and women produce physical children. But the gospel itself also produces offspring. We see this in how Isaiah foretells the death of Jesus: It was the will of the Lord to crush him; he has put him to grief; when his soul makes an offering for guilt, he shall see his offspring. (Isa. 53:10)
