Here then make use of Jesus Christ, the great Revealer of God and his will to the blinded world, and the great Confirmer of the divine authority of his word. Life and immortality are brought more fully to light by the gospel, than ever they were by any other means. Moses and the prophets did bring with their doctrine sufficient evidence of its credibility. But Christ hath brought both a fuller revelation, and a fuller evidence to help belief. An inspired prophet, which proveth his inspiration to us, is a credible messenger: but when God himself shall come down into flesh, and converse with man, and teach him the knowledge of God, and the way to life, and tell him the mysteries of the world to come, and seal his testimony with unquestionable proofs, who will not learn of such a Teacher? and who will deny belief to such a Messenger, except absurd, unreasonable men? Remember, then, when ignorance or unbelief would hinder your access to God, that you have the ablest Teacher and the surest Witness to acquaint you with God in all the world. If God had sent an angel from heaven, to tell you what he is, and what he requireth of you, and what he will do for you, would it not be very acceptable to you? But he hath done much more; he hath sent his Son:[86] the Deity itself hath appeared in flesh: he that hath seen God, and he that is God, hath come among men to acquaint them with God. His testimony is more sure and credible than any angel's. Heb. i. 1-3, "God, who at sundry times and in divers manners spake in times past to the fathers by the prophets, hath in these last days spoken to us by his Son." John i. 18, "No man hath seen God at any time; the only-begotten Son, who is in the bosom of the Father, he hath declared him." We have "neither heard the voice of God, nor seen his shape," John v. 37. "No man hath seen the Father, save he which is of God; he hath seen the Father," John vi. 46. "No man knoweth the Father, save the Son, and he to whomsoever the Son will reveal him," Matt. xi. 27. What more can we desire, that is short of the sight of the glory of God, than to have him revealed to us by a messenger from heaven, and such a messenger as himself has seen him, and is God himself? Plato and Plotinus may describe God to us according to their dark conjectures; something we may discern of him by observing his works; but Christ hath declared what he saw, and what he knew, beyond all possibility of mistake. And lest his own testimony should seem questionable to us, he hath confirmed it by a life of miracles, and by rising from the dead himself, and ascending visibly to heaven; and by the Holy Ghost, and his miraculous gifts, which he gave to the messengers of his gospel. Had it been no more than his resurrection from the dead, it had been enough to prove the utter unreasonableness of unbelief.
2. It is also a great impediment to the soul in its approach to God, that infinite distance disableth us to conceive of him aright. We say, as Elihu, Job xxxvi. 26, "Behold, God is great, and we know him not." And, indeed, it is impossible that mortal man should have any adequate apprehensions of his essence. But in his Son he hath come down to us, and showed himself in the clearest glass that ever did reveal him. Think of him therefore as he appeared in our flesh; as he showed himself in his holiness and goodness to the world. You may have positive thoughts of Jesus Christ; though you may not think that the Godhead was flesh, yet may you think of it as it appeared in flesh. It may quiet the understanding to conceive of God as incarnate, and to know that we cannot yet know him as he is, or have any adequate conceptions of him. These may delight us till we reach to more.
3. It hindereth the soul's approach to God, when the infinite distance makes us think that God will not regard or take notice of such contemptible worms as we: we are ready to think that he is too high for our converse or delight. In this case the soul hath no such remedy, as to look to Christ; and see how the Father hath regarded us, and set his heart upon us, and sent his Son to seek and save us. Oh wonderful, astonishing condescension of eternal love! Believe that God assumed flesh to make himself familiar with man; and you can never question whether he regard us, or will hold communion with us.
