By faith Sarah herself received the ability to conceive, and she bore a child when she was beyond the proper age, because she considered him faithful who had made the promise.
And behold, yoʋr relative Elizabeth has also conceived a son in her old age, and this is the sixth month for her who was called barren.
That is, it is not the children of the flesh who are the children of God; rather, the children of the promise are counted as descendants.
But the son of the slave woman was born according to the flesh, while the son of the free woman was born through the promise.
Let us hold fast to the confession of our hope without wavering, for he who promised is faithful.
