You come next to an improvement upon the whole, where you make a comparison between the heathens and the gospel; shewing how far the gospel helpeth the light the heathens had, in their pursuit after your holiness. But still the excellency of the gospel, as you have vainly dreamt, is to make improvement first of the heathen principles; such good principles, say you, 'as were by the light of nature dictated to them' (p. 133). As,
1. 'That there is but one God; that he is infinitely perfect,' &c.
2. 'That we owe our lives, and all the comforts of them to him.'
3. 'That he is our sovereign Lord.'
4. 'That he is to be loved above all things' (p. 136).
Ans. 1. Seeing all these are, and may be known, as you yourself confess, by them that have not the gospel; and I add, nor yet the Holy Ghost, nor any saving knowledge of God, or eternal life: Therefore it cannot be the design of Jesus Christ by the gospel to promote or help forward this knowledge, simply from this principle, viz. Natural light, and the dictates of it. My reason is, because when nature is strained to the highest pin, it is but nature still; and so all the improvement of its light and knowledge is but an increase of that which is but natural. 'But [saith Paul] the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned' (1 Cor 2:14).
But the gospel is the ministration of the Spirit; a revelation of another thing than is found in, or can be acquired by, heathenish principles of nature.
I say, a revelation of another thing; or rather, another discovery of the same. As, 1. Concerning the Godhead; the gospel giveth us another discovery of it, than is possible to be obtained by the dictates of natural light; even a discovery of a trinity of persons, and yet unity of essence, in the same Deity (1 John 5:1,5,8). 2. The light of nature will not shew us, that God was in Christ, reconciling the world to himself. 3. The light of nature will not shew us, that we owe what we are, and have, to God, because we are the price of the blood of his Son. 4. The light of nature will not shew, that there is such a thing as election in Christ. 5. Or, that there is such a thing, as the adoption of children to God, through him. 6. Nor, that we are to be saved by faith in his blood. 7. Or, that the man Christ shall come from heaven to judgment. These things, I say, the light of nature teacheth not; but these things are the great and mighty things of the gospel, and those about which it chiefly bendeth itself, touching upon other things, still as those that are knowable, by a spirit inferior to this of the gospel.
Besides, as these things are not known by the light of nature, so the gospel, when it comes, as I also told you before, doth implant in the soul another principle, by which they may be received, and from which the soul should act and do, both towards God and towards men; as namely the Holy Ghost, faith, hope, the joy of the Spirit, &c.
