Calling on the Everlasting God

Genesis 21:1

The chapter opens with God, not with Sarah’s body or Abraham’s age. “The LORD visited Sarah as he had said, and the LORD did unto Sarah as he had spoken.” The two clauses say almost the same thing, and the repetition is intentional. A quarter century of promises lies behind them: offspring in 12:2 and 15:4, a son through Sarah in 17:16–19, and a fixed season in 18:10, 14. What God had said He now did. The narrator wants the reader to see the birth first as an act of divine faithfulness and only afterward as a family event.

The verb “visited” describes God turning His attention to someone and intervening decisively. It can bring judgment, but here, as when Joseph later assures his brothers that God will surely visit them (50:24), it brings rescue and blessing. Notice also that Sarah is named twice and Abraham not at all. The woman who had laughed behind the tent door, who had once proposed Hagar as a substitute, is the direct object of God’s grace. Her barrenness, recorded as early as 11:30, is now answered.

This birth ran against the ordinary course of nature, and the New Testament treats it as a work of divine power received by faith. Paul calls Isaac the son “by promise” in contrast to the son “after the flesh” (Galatians 4:23), and Hebrews says Sarah “received strength to conceive seed” because “she judged him faithful who had promised” (Hebrews 11:11). Isaac’s birth is therefore one link in a chain of saving interventions that reaches its climax when God sent His Son. The same Lord who visited Sarah would later visit and redeem His people in the incarnation (Luke 1:68).

The verse sets a pattern for reading the rest of the chapter. Everything that follows, the naming, the circumcision, the separation of Ishmael, the rescue in the desert, and the oath at Beersheba, flows from a God whose word is reliable.
