For it is written that Abraham had two sons, the one by a bondwoman, and the other by a free.

Now the son of the bond-maid was born after the flesh, but that by the free woman was by promise.

But the Jerusalem above is free, which is the mother of us all.

But what saith the scripture? "Cast out the bond-woman and her son for the son of the bond-maid shall in no wise inherit with the son of the free woman."

So then, brethren, we are not the children of the bondwoman, but of the free.

STAND fast therefore in the liberty with which Christ has made you free, and be not again held under a yoke of bondage.
