Charming view of Abram's faith and humility. So, depend upon it more or less, are all Abram's spiritual children. See Daniel 8:17 - Daniel 10:15; Revelation 1:17
Reader! do not overlook the expression. God calls it his Covenant. Yes! a Covenant ordered in all things, and sure, must be God's. And it is the happiness of his people, that He who hath made it, undertakes for its accomplishment. Jeremiah 32:40; Isaiah 54:10. Under this verse, it may not be amiss to remark, that Abram had more children naturally considered, than any other of the Patriarchs; and spiritually, who shall number them? Romans 4:10; Revelation 7:9.
