In this excerpt, Thomas Schreiner reflects on the story of Sarah, Hagar, and Isaac, highlighting a surprising biblical tension: Sarah speaks what is true—yet does so with a sinful attitude.

Schreiner shows how Scripture itself affirms Sarah’s words as aligned with God’s promise, even while her heart remains flawed. This passage reveals how God’s purposes move forward even through imperfect people, and how truth and sin can coexist in complex ways within human actions.

Ultimately, the promise of God is fulfilled through Isaac, pointing to the unfolding plan of redemption throughout Scripture.
