Genesis 17:20

As for Ishmael, I have heard thee; I have blessed him - That is, I have many blessings in store for him. His posterity shall be numerous; I will multiply him exceedingly; They shall be considerable; twelve princes shall he beget. We may charitably hope that spiritual blessings also were bestowed upon him, though the visible church was not brought out of his loins.

Genesis 21:13

The casting out of Ishmael was not his ruin. He shall be a nation because he is thy seed - We are not sure that it was his eternal ruin. It is presumption to say, that all these who are left out of the external dispensation of God's covenant are excluded from all his mercies. Those may be saved who are not thus honoured.
