It is just as it was with Abraham--'He had faith in God, and his faith was regarded by God as righteousness.'

You see, then, that those whose lives are based on faith are the Sons of Abraham.

And Scripture, foreseeing that God would pronounce the Gentiles righteous as the result of faith, foretold the Good News to Abraham in the words--'Through thee all the Gentiles shall be blessed.'

And, therefore, those whose lives are based on faith share the blessings bestowed upon the faith of Abraham.

And this he did that the blessing given to Abraham might be extended to the Gentiles through their union with Jesus Christ; that so, through our faith, we also might receive the promised gift of the Spirit.

Now it was to Abraham that the promises were made, 'and to his offspring.' It was not said 'to his offsprings,' as if many persons were meant, but the words were 'to thy offspring,' showing that one person was meant--and that was Christ.

If our heritage is the result of Law, then it has ceased to be the result of a promise. Yet God conferred it on Abraham by a promise.

And, since you belong to Christ, it follows that you are Abraham's offspring and, under the promise, sharers in the inheritance.

Scripture says that Abraham had two sons, one the child of the slave-woman and the other the child of the free woman.
