Covenant Confirmed

Thirteen long years after Ishmael is born, God finally speaks to Abram again. He confirms his covenant with Abram, changing his name to Abraham, promising him a son named Isaac through Sarah, and giving him the sign of circumcision. We are people of the new covenant. This new covenant involves a new kind of circumcision, the “circumcision of the heart, by the Spirit” (Rom 2:29).
