But Abram did not know how to wait; and Sarai takes no happy part in the action of this chapter. It is first "that which is natural," though we can also add, "afterward that which is spiritual." Flesh is impatient, and seeks at once the accomplishment in its own way. She proposes her Egyptian bondmaid, Hagar, and, Abram hearkening instead of walking by faith, the maid conceives, and her mistress is despised. The Epistle to the Galatians gives the certain clue to what we else might never have understood. It is the covenant of Sinai which she represents, answering to Jerusalem which now is, and is in bondage with her children. The law works not peace but wrath, not the accomplishment of the promise but fleshly pride, and a child born in sorrow who cannot be heir. What a contrast to blessing and praise through the royal priest in chapter 14, or the altars of chapters 12, 13! If the justified man take up the law (save to convict others), no wonder if the issue be disappointment on all hands. Such is the solemn admonition of our chapter. The law is good if one use it lawfully; but it is not applied rightly to righteous persons, but to lawless. The believer has no more to do with it for himself now, than Abram then should have taken Hagar. It is interesting to observe that as Hagar was really of Egypt and a slave, so she typically is mount Sinai in Arabia, the covenant that genders to bondage (Gal. 4). The flesh, the world, and the law work together, and the gospel delivers the believer from all by the death of Christ, as unbelief exposes to mischief from them all.
