3. Various are the dispensations of God's grace unto his own. To some he giveth a greater, to others a lesser measure of knowledge of the mysteries of the kingdom of heaven; and to one and the same person, more at one time than at another. Various are his manifestations and out-lettings of grace and love. Small beginnings may come to much at length. Thomas, and the rest of the disciples, had but little clear and distinct apprehensions of the way of salvation through Jesus Christ; and yet, ere all was done, they attained to such a measure of understanding in the mysteries of God, as that we are said to be "built upon the foundation of the apostles, Jesus Christ himself being the chief corner-stone," Eph. ii. 20. This should teach the best much sobriety, and not to judge of all by themselves; or to think, that God's way with them must be a standard or a rule whereby to judge of all the rest; as if his way of dealing were one and the same with all. 4. The knowledge of Christ is all. Know him, and we know heaven and the way to it; for upon this ground doth Christ make good what he said, touching their knowing whither he went, and the way; and answereth the objection that Thomas did propose, viz. because he was the way, &c., and they being acquaint with him, (which here is presupposed,) were not ignorant of the place whither he was going, nor of the way leading thither. The knowledge then of Jesus Christ is a true and full compend of all saving knowledge. Hence it "is life eternal to know him," John xvii. 3. "They that know him, know the Father," John xiv. 9. and viii. 19. "They that see him, see the Father also," John xiv. 9. "He is in the Father, and the Father in him," John xiv. 10, 11. and x. 38. and xvii. 21. And so knowing him they know heaven; for what is heaven else but the presence and glorious manifestations of the Father; for when Christ speaks of his going to heaven, he saith, "He was going to the Father." So knowing him, they know the way, both how Christ was to go to heaven as our cautioner, head, and attorney, and how we must follow. Let then a man have never so much knowledge, and be acquainted with the mysteries of all arts and sciences, and with the depths of nature, and intrigues of states, and all the theory of religion; if he be unacquainted with Jesus, he knoweth nothing as he ought to know. And upon the other hand, let a poor soul that is honest, and hath some knowledge of, and acquaintance with him, be satisfied, though it cannot discourse nor dispute, nor speak to cases of conscience, as some others; if we know him, it matters not though we be ignorant of many things, and thereby become less esteemed of by others. Here is the true test, by which we may take a right estimate of our own, or of others' knowledge. The true rule to try knowledge by, is not fine notions, clear and distinct expressions, but heart-acquaintance with him; "in whom are hid all the treasures of wisdom and knowledge," Col. ii. 3.
