4. That as we are, we cannot see God; "for no man hath seen him," Matt. xi. 27. John iv. 46; for he is an invisible God, 1 Tim. i. 17. Heb. xi. 27. "He dwelleth in light which no man can approach unto. Him no man hath seen, nor can see," 1 Tim. vi. 16. 1 John iv. 12. 5. That all that knowledge of God which is saving, is to be found in Christ, who is the "brightness of his glory, and the express image of his person," Heb. i. 2; "and the image of the invisible God," Col. i. 15; and is for this end come out from the bosom of the Father, that he might acquaint us with him, and with all his secrets, John i. 18. Matt. xi. 27, so far as is needful for us to know. He is God incarnate, that in him we may see the invisible. Thus "God is manifest in the flesh," 1 Tim. iii. 16; "and the Word was made flesh, and dwelt among us," John i. 14. 6. That therefore if we would see and know God, we must go to Christ, who is the temple in which God dwelleth and manifesteth his glory; and in and through him, must we see and conceive of God. The light that we get of the knowledge of the glory of God, must be in the face of Jesus Christ, 2 Cor. iv. 6; that is, in the manifestations that Christ hath made of himself, in his natures, offices, ordinances, works, dispensations of grace, mediate and immediate, &c. And thus doth God, who commanded the light to shine out of darkness, "cause this light of the knowledge of his glory shine into our hearts," viz. in the face of Jesus Christ, that is, in the dispensations of grace in the gospel, which is the glorious gospel of Christ, 2 Cor. iv. 4, and, as it were, the face of Jesus Christ; for as by the face a man is best known and distinguished from others, so Christ is visibly, and discernibly, and manifestly, seen and known, in and by the gospel dispensations; there are all the lineaments and draughts of the glory of God which we would know, lively and clearly to be seen. So then, if we would make use of Christ for this end, that we may win to a right sight of God, and suitable conceptions of his glory, we would consider those things: 1. We would live under the sense and thorough conviction of the greatness and incomprehensibleness of God, as being every way past finding out; and also under the conviction of our own darkness and incapacity to conceive aright of him, even as to what he hath revealed of himself. 2. We would know, that what the works of creation and providence declare and preach forth of God, though it be sufficient to make heathens and others that do not improve the same to a right acknowledging of him, inexcusable, as Paul teacheth us, Rom. i. 20; yet all that is short of giving to us that saving knowledge of him, which must be had, and which is life eternal, John xvii. 2.
