Why circumcision and how is it a sign?
Robert Sungenis holds that God commanded circumcision after Abraham laughed at the promise of a son, marking the very organ through which that promise would come. He reads it as both a covenant sign and a standing reminder of Abraham's unbelief, and as a figure of Christ, who was cut and bled for our salvation.
Why circumcision and how is it a sign?
Answer
God commanded circumcision after Abraham laughed at His promise of a son. Abraham doubted God’s word, so God made him mark the very organ through which the promise would come. It was a covenant sign and a reminder of Abraham’s unbelief. Every time he saw it, he remembered that God’s promises do not fail. It also prefigures Christ, who was cut and bled for our salvation. The covenant mark on Abraham pointed forward to the cross.
