Quick answer

Abraham is a hundred years old at Isaac's birth. The note underscores the miraculous nature of the birth.

Overview

Abraham's advanced age highlights that Isaac's birth was humanly impossible and wholly the work of God. The promise was fulfilled when both parents were long past the age of childbearing, magnifying God's power and faithfulness. Such impossibilities, made possible by God, prepare the reader to trust the God who later raises the dead and gives life through the gospel.

Christ at the center

From the first promise that the seed of the woman would crush the serpent (3:15), through Abraham's blessing to all nations and Judah's coming ruler, Genesis sows every seed that flowers in Christ — the true offspring, the better Adam, the ram caught for Isaac.
