Now, for a ground to our following discourse, I would press the solid, thorough and sensible apprehension of this, without which there will be no use-making or application of Christ; "for the whole need not the physician, but the sick;" and Christ is "not come to call the righteous, but sinners to repentance," Matt. ix. 12. Mark ii. 17. Yea, believers themselves would live within the sight of this, and not forget their frailty; for though there be a change wrought in them, yet they are not perfect, but will have need of Christ as the way, the truth, and the life, till he bring them in, and set them down upon the throne, and crown them with the crown of life. And, O happy they, who must not walk on foot without this guide leading them by the hand, or rather carrying them in his arms. Let all them who would make use of Christ remember what they were, and what they are, and keep the sense of their frailty and misery fresh; that seeing their need of him, they may be in better case to look out to him for help and supply, and be more distinct in their application of him. The _second_ general is, that Christ is a complete mediator, thoroughly furnished for all our necessities. Are we at a distance from the Father? He is a way to bring us together. Are we wandered out of the way? He is the way to us. Are we blind and ignorant? He is the truth. Are we dead? He is the life. Concerning this fulness and completeness of his, we would mark these things: 1. That he is thoroughly furnished with all things we stand in need of; the way, the truth, and the life. He hath eye-salve, clothing, gold tried in the fire, &c. "For the Spirit of the Lord is upon him, and hath anointed him," Isa. lxi. 1. 2. He is suitably qualified, not only having a fulness, and an all-fulness, so that whatever we need is to be had in him, but also a suitable fulness answering our case to the life. Are we out of the way? He is the way. Are we dead? He is life, &c. 3. He is richly qualified with this suitable good. He hath not only "wisdom and knowledge," but "treasures of it," yea, "all the treasures" thereof, Col. ii. 3. There is fulness in him; yea, "it hath pleased the Father that in him should all fulness dwell," Col. i. 19. Yea, "the fulness of the Godhead dwelleth in him bodily," Col. ii. 9. 4. Hence this is an up-making completeness and fulness; for we are said to be "complete in him," Col. ii. 10. And he is said to "be all in all," Col. iv. 11. "He filleth all in all," Eph. i. 23. 5. It is also a satisfying completeness. The eye is not satisfied with seeing, nor the ear with hearing. The avaricious man is not satisfied with gold, nor the ambitious man with honour; but still they are crying with the loch leech, give, give! But the man who getteth Christ is full; he sitteth down and cryeth, enough, enough! And no wonder, for he hath all; he can desire no more; he can seek no more; for what can the man want that is complete in him?
