8. The _sixth_ cause why God will have our righteousness to be apprehended by faith, is found in his truth and promise, on which our faith entirely rests, and by which God declared and promised righteousness to Abraham, and to all his faithful seed. Whence St. Paul argues, that “our righteousness must be of faith, that it might be by grace; to the end that the promise might be sure.” Rom. 4: 16. Upon this promise of grace, fulfilled in Christ, has God established our righteousness and salvation, as the same apostle in another place more fully asserts: “Even as Abraham,” says he, “believed God, and it was accounted to him for righteousness. Know ye therefore that they which are of faith, the same are the children of Abraham.” And the Scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham: saying, In thee shall all nations be blessed (Gen. 12:3). “So then they which be of faith, are blessed with faithful Abraham.” Gal. 3:6-9. And thus “grace and truth are come by Jesus Christ.” John 1:17. 9. _Seventhly_, God has made his grace, and the merit of Christ, the foundation of our righteousness, that Christ alone may have the honor of it. Isa. 45:22-24; 53:11. “In him alone is our help.” Hos. 13:9. He is the beginning, middle, and end of our righteousness and salvation, so that “every mouth may be stopped.” Rom. 3:19. For we are “saved by grace through faith; not of works, lest any man should boast.” Eph. 2:8, 9. But if our righteousness were founded on our own works and merits, there would then be no room for grace, nor should we have occasion for mercy or pardon of sin, “for which every one that is godly doth pray.” Ps. 32:6. Moreover, there would be no place for humility, nor for the fear of God; neither would faith and prayer turn to any great account; yea, we should have no need of a Mediator, Redeemer, and Saviour. Christ would have then died in vain; and we should be obliged, both by an external and an internal obedience, perfectly to fulfil the whole law. We should remain under the curse, have fallen from grace, and have lost Christ; as St. Paul expressly testifies in Gal. 5:3, 4. So that the doctrine of justification by _works_, in the sight of God, is altogether inconsistent with the whole Scripture, both of the Old Testament and the New, and with our holy Christian faith.
