TSK · Galatians 4:30

Therefore she said to Abraham, "Cast out this handmaid and her son! For the son of this handmaid will not be heir with my son, Isaac."

For what does the Scripture say? "Abraham believed God, and it was accounted to him for righteousness."

God didn't reject his people, which he foreknew. Or don't you know what the Scripture says about Elijah? How he pleads with God against Israel:

The Scripture, foreseeing that God would justify the Gentiles by faith, preached the Good News beforehand to Abraham, saying, "In you all the nations will be blessed."

Or do you think that the Scripture says in vain, "The Spirit who lives in us yearns jealously"?
