Can you not see, then, that all those who “believe God” are the real “sons of Abraham”? The scripture foreseeing that God would justify the Gentiles “by faith”, really proclaimed the Gospel centuries ago in the words spoken to Abraham, ‘In you all the nations shall be blessed.’

And the Law is not a matter of faith at all but of doing, as, for example, in the scripture: ‘The man who does them shall live by them.’

Is the Law then to be looked upon as a contradiction of the promise? Certainly not, for if there could have been a law which gave men spiritual life then law would have produced righteousness (which would have been, of course, in full harmony with the purpose of the promise). But, as things are, the scripture has all men “imprisoned”, because they are found guilty by the Law, that to men in such condition might come to release all who believe in Jesus Christ.
