III. To show the truth of the doctrine; that is, to show that there is such a thing as that spiritual light that has been described, thus immediately let into the mind by God. And here I would show briefly that this doctrine is both scriptural and rational.
First, ’Tis scriptural. My text is not only full to the
purpose but ’tis a doctrine that Scripture abounds in. We are there
abundantly taught that the saints differ from the ungodly in this, that they
have the knowledge of God, and a sight of God, and of Jesus Christ. I shall
mention but a few texts of many. 1 John iii. 6, “Whosoever sinned hath not seen
him, nor known him.” 3 John 11, “He that doeth good is of God: but he that
doeth evil hath not seen, God.” John xiv. 19, “The world seeth me no more, but
ye see me.” John xvii. 3, “And this is eternal life, that they might know thee
the only true God, and Jesus Christ, whom thou hast sent.” This knowledge, or
sight of God and Christ, can’t be a mere speculative knowledge; because it is
spoken of as a seeing and knowing wherein, they differ from the ungodly. And by these Scriptures it must not only be a different knowledge in degree and
circumstances, and different in its effects; but it must be entirely different
in nature and kind.
The Scripture also speaks plainly of such a knowledge of the word of God as has been described, as the immediate gift of God, Psalm. cxix. 18: “Open thou mine eyes, that I may behold wondrous things out of thy law.” What could the Psalmist mean when he begged God to open his eyes? Was he ever blind? Might he not have resorted to the law and seen every word and sentence in it when he pleased? And what could he mean by those “wondrous things”? Was it the wonderful stories of the creation and deluge, and Israel’s passing through the Red Sea, and the like? Were his eyes not open to read these strange things when he would? Doubtless, by “wondrous things” in God’s law, he had respect for those distinguishing and wonderful excellencies, and marvelous manifestations of the divine perfections and glory, that there was in the commands and doctrines of the word, and those works and counsels of God that were there revealed. So, the Scripture speaks of a knowledge of God’s dispensation, and covenant of mercy, and way of grace towards his people, as peculiar to the saints, and given only by God, Psalm. xxv. 14: “The secret of the Lord is with them that fear him, and he will show them his covenant.”
