The law saith nothing of faith in the Mediator; though faith in God be commanded in the first precept, yet faith in Christ is not commanded by the law as that by which the soul shall live. For that which the law saith is: Do this and live: The man that doeth the things contained in the law, shall live in them; life, in the law, is promised to those who do the things which it requireth; not to them who, have failed in their performances, yet accept of the Lord Jesus Christ as the Redeemer which God hath sent, and believe in him who justifieth the ungodly. For that by the life promised to the observation of the law, not a temporal life only is to be understood, but eternal life also, is plain from our Saviour's application of it to the young man, inquiring about the way to eternal life, Matthew 19:16,17 Lu 10:28.
