One of the great ironies of history

In one of the great ironies of history that only God could bring about we see him promise that the Gentiles will be brought into the Kingdom. The faith of Abraham that belonged to Abraham's descendants was to become the faith of the entire world, with all men of faith becoming the seed of Abraham.

Arise, shine, for your light has come,
and the glory of the Lord has risen upon you.
For behold, darkness shall cover the earth,
and thick darkness the peoples;
but the Lord will arise upon you,
and his glory will be seen upon you.
And nations shall come to your light,
and kings to the brightness of your rising. (Isa 60:1-3)

Such was the in-pouring of the nations that their numbers dwarfed Israel. Abraham's descendants would number as stars and sand (Genesis 22:17). And irony of ironies, Israel did not want to be part of the kingdom; the children of the flesh refused to be children of the faith. The people of the promise would not accept the promise, but to those who saw the light of the promise the promise also came; and they came to the promise. The Gentiles join with Israel and outnumber Israel, but not all Israel is Israel (Romans 9:6). Yet when the time of the Gentiles has ended, will not God include the sons of the flesh? But not as descendants by flesh, rather by faith (Romans 11:23).
