Israel (2) - Multitude

God is faithful. He will never break a covenant he has made with his people. He made a covenant with Abraham that still stands.

I will make you into a great nation,
and I will bless you;
I will make your name great
and you will be a blessing.
I will bless those who bless you,
and whoever curses you I will curse;
and all peoples on earth
will be blessed through you (Gen 12:2-3).

God made Abraham great, but all the peoples of the earth have not yet been blessed through him. His descendants will have to be filled with the Spirit before this is fulfilled.
God also promised Abraham that his descendants would be a huge multitude.

Look now toward heaven, and count the stars if you are able to number them. So shall your descendants be (Gen 15:5).

This promise cannot be fulfilled by physical descendants. The total number of Jews is still well short of the stars in the sky. Under the new covenant, all who believe in Jesus are counted as children of Abraham. When the full number of those who will come to faith in Jesus are added to Abrahams physical descendants this promise will easily be fulfilled.

God has not broken the covenants made in the Old Testament. His covenant with Abraham still stands. All those who believe in Jesus are counted as children of Abraham to make his descendants as many as the stars in the sky.
