Does God then give you the Spirit and work miracles among you by your doing the works of the law or by your believing what you heard?

For all who rely on doing the works of the law are under a curse, because it is written, "Cursed is everyone who does not keep on doing everything written in the book of the law."

But the law is not based on faith, but the one who does the works of the law will live by them.

Now the promises were spoken to Abraham and to his descendant. Scripture does not say, "and to the descendants," referring to many, but "and to your descendant," referring to one, who is Christ.

What I am saying is this: The law that came four hundred thirty years later does not cancel a covenant previously ratified by God, so as to invalidate the promise.

For it is written: "Rejoice, O barren woman who does not bear children; break forth and shout, you who have no birth pains, because the children of the desolate woman are more numerous than those of the woman who has a husband."

But what does the scripture say? "Throw out the slave woman and her son, for the son of the slave woman will not share the inheritance with the son" of the free woman.

This persuasion does not come from the one who calls you!
