3. Every lecture, or reading of this old law, is as a fresh hood-winking of its disciples, and a doubling of the hindrance of their coming to Christ for life. 'But their minds were blinded, for until this day, remaineth the same vail untaken away in reading of the old testament; which vail is done away in Christ. But even unto this day, when Moses is read, the vail is upon their hearts' (2 Cor 3:14,15).
And let the reader note, that all these things attend the doctrine of morals: the ceremonies being in themselves more apt to instruct men in the knowledge of Christ, they being by God's ordination, figures, shadows, representations, and emblems of him; but the morals are not so, neither, as written in our natures, nor as written and engraven in stones (Gal 3:24). Wherefore, your so highly commended obedient temper of mind, you intending thereby an hearty compliance before faith, with morals for righteousness, is so far off from being an excellent temper, and a necessary qualification, to help a man to a firm belief, and right understanding of the gospel; that it is the most ready way of all ways in the world, to keep a man perpetually blind, and ignorant thereof. Wherefore the apostle saith, that the vail, the ignorance, cannot be taken away, but when the heart shall turn to the Lord, that is, from the doctrine of morals, as a law and covenant in our natures, or, as it was written and engraven in stones, to Christ for mercy to pardon our transgressions against it, and for imputative righteousness to justify us from it. While Moses is read, the vail is over the heart; that is, while men with their minds stand bending also to do it. But mark, when it, the heart, shall turn to the Lord, or to the word of the gospel, which is the revelation of him, then the vail shall be taken away.
And hence it will not be amiss, if again we consider how the Holy Ghost compareth, or setteth one against another, these two administrations.
The law he calls the letter, even the law of morals, that law that was written and engraven in stones. The other ministration, he calls the ministration of the spirit, even that which Christ offered to the world, upon believing.
Again, he denieth himself to be a minister of the law of morals. He hath made us able ministers of the New Testament, not of the letter, or law; but of the spirit or gospel. The reason is, for the letter, or law, can do nothing but kill, curse, or condemn; but the spirit, or the gospel, giveth life. Farther, in comparing, he calls the law, the ministration of death, or that which layeth death at the doors of all flesh; but the gospel, the ministration of righteousness, because, by this ministry, there is a revelation of that righteousness that is fulfilled by the person of Christ; and to be imputed for righteousness to them that believe, that they might be delivered from the ministration of death. How then? Hath the ministration of God no glory? Yes, forasmuch as it is a revelation of the justice of God against sin. But yet again, its glory is turned into no glory, when it is compared with that which excelleth. 'But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away; how shall not the ministration of the Spirit be rather glorious? For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory. For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth' (2 Cor 3:7-10).
So then, your obedient temper of mind, forasmuch as it respecteth the law of morals, and that too, before faith, or a right understanding of the gospel, is nothing else but an obedience to the law, a living to death, and the ministration of condemnation; and is a persuading the world, that to be obedient to that ministration, that is not the ministration of the gospel, but holdeth its disciples in blindness and ignorance, in which it is impossible Christ should be revealed, is an excellent, yea, a necessary qualification to prepare men for a firm belief, and a right understanding of the gospel of Christ, which yet even blindeth, and holdeth all blind that are the followers of that ministration. I come now to your proof, which indeed is no proof of this anti-gospel assertion, but texts abused, and wrested out of their place, to serve to underprop your erroneous doctrine. The first is, 'If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself' (John 7:17, p. 268).
Ans. This scripture respecteth not at all the moral law, or obedience to the dictates of human nature, as an acceptable qualification precedent to faith; or that, for the sake of which God will give men faith in, and a right understanding of the gospel, but is itself an immediate exhortation to believing, with a promise of what shall follow; as who shall say, The Father hath sent me into the world to be salvation to it, through faith in my blood: My Father's will therefore is, 'that men believe in me'; and if any will do his will, he shall know of the doctrine, he shall feel the power thereof, by the peace and comfort that will presently possess the soul, and by the holy effects that follow.
That this is the true exposition of this place will be verified if you consider, that to do the will of God, in a New Testament sense, is to be taken under a double consideration. 1. As it respecteth Christ. 2. Man.
1. As it respecteth Christ, so it concerns his completing the redemption of man by himself, by his own personal performances (John 6:38,39; Heb 10:5-10).
2. As it respecteth man, it doth first and immediately respect our believing on him for remission of sins and eternal life. 'And this is the will of him [the Father] which sent me [saith Christ] that every one that seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day' (John 6:40). This then is the will of God; that men do believe in Jesus Christ.
