Christians would emphasize the spiritual connection to Abraham by faith. In this passage Paul asks a different question, “Who is your mother?” Abraham had two wives from whom he fathered two sons. By means of the literary device of allegory, Paul argued that salvation by grace through faith is both taught in the Old Testament and beautifully illustrated in it as well.
