1. Because faith, having laid hold upon Christ, hath found him 'in whom are hid all the treasures of wisdom and knowledge' (Col 2:3). In him therefore it finds and sees those heights and depths of gospel mysteries that are nowhere else to be found; nay, let a man be destitute of faith, and it is not possible he should once think of some of them.
2. By this means the Holy Spirit is plentifully received (Gal 3:1-3). Now the Spirit of God is a spirit of wisdom and revelation; but yet so as in the knowledge of Christ; otherwise the Spirit will show to man not any mighty thing, its great delight being to open Christ and to reveal him unto faith (Eph 1:17). Faith indeed can see him, for that is the eye of the soul; and the Spirit alone can reveal him, that being the searcher of the deep things of God; by these therefore the mysteries of heaven are revealed and received. And hence it is that the mystery of the gospel is called the 'mystery of faith,' or the mystery with which faith only hath to do (1 Tim 3:9).
Wouldst thou, then, know the greatest things of God? Accustom thyself to the obedience of faith,[34] live upon thy justifying righteousness, and never think that to live always on Christ for justification is a low and beggarly thing, and as it were a staying at the foundation; for let me tell you, depart from a sense of the meritorious means of your justification with God, and you will quickly grow light, and frothy, and vain. Besides, you will always be subject to errors and delusions; for this is not to hold the head from or through which nourishment is administered (Col 2:19). Further, no man that buildeth forsakes the good foundation; that is the ground of his encouragement to work, for upon that is laid the stress of all; and without it nothing that is framed can be supported, but must inevitably fall to the ground.
Again; why not live upon Christ alway? and especially as he standeth the mediator between God, and the soul, defending thee with the merit of his blood, and covering thee with his infinite righteousness from the wrath of God and curse of the law. Can there be any greater comfort ministered to thee than to know thy person stands just before God? Just and justified from all things that would otherwise swallow thee up? Is peace with God and assurance of heaven of so little respect with thee that thou slightest the very foundation thereof, even faith in the blood and righteousness of Christ? and are notions and whimsies of such credit with thee that thou must leave the foundation to follow them? But again; what mystery is desirable to be known that is not to be found in Jesus Christ, as Priest, Prophet, or King of saints? In him are hid all the treasures of them, and he alone hath the key of David to open them (Col 2:1,2; Rev 3:7). Paul was so taken with Jesus Christ, and the knowledge of this, that he was crucified for us, that he desired, nay, determined not to know any thing else among the Corinthians, that itched after other wisdom (1 Cor 2:2).
Object. But I see not that in Christ now, that I have seen in him in former days. Besides, I find the Spirit lead me forth to study other things.
Answ. To the first part of this objection I would answer several things.—The cause why thou seest not that in Christ now, which thou hast seen in him in former days, is not in Christ, but in thy faith; he is the same, as fresh, and as good, and as full of blessedness, as when thou didst most rejoice in him (Heb 1:11,12). And why not now, as well as formerly? God is never weary of being delighted with Jesus Christ; his blood is always precious with God; his merits being those in which justice hath everlasting rest, why shouldst thou wander or go about to change thy way? (Prov 8:30; Jer 2:36). Sin is the same as ever, and so is the curse of the law. The devil is as busy as ever; and beware of the law in thy members. Return, therefore, to thy rest, O soul! for he is thy life, and the length of thy days. Guilt is to be taken off now, as it was years ago; and whether thou seest it or no, thou sinnest in all thy works. How, then, canst thou stand clear from guilt in thy soul who neglectest to act faith in the blood of the Lamb? There thou must wash thy robes, and there thou must make them white (Rev 7:14,15). I conclude, then, thou art a polluted, surfeited, corrupted, hardened creature, whosoever thou art, that thus objectest.
But I find, sayest thou, as if the Spirit led me forth to study other matters.
Answ.—First. What other matters? What matters besides, above, or beyond the glorious gospel of Jesus Christ, and of our acceptance with God through him? What spirit, or doctrine, or wisdom soever it be that centres not in, that cometh not from, and that terminates not within, the bonds of the gospel of Jesus Christ, is not worthy the study of the sons of God; neither is it food for the faith of Jesus Christ, for that is the flesh of Christ, and that is eternal life (John 6:5). Whither will you go? Beware of the spirit of Antichrist; for 'many false spirits are gone out into the world.' I told you before, that the Spirit of God is 'the Spirit of wisdom and revelation in the knowledge of Christ,' and that without and besides the Lord Jesus it discovereth nothing (Eph 1:17). It is sent to testify of him; it is sent to bring his words to our remembrance; it is sent to take of his things and show them unto us (John 14,15,16). Wherefore, never call that the Spirit of Jesus which leads you away from the blood and righteousness of Christ; that is but the spirit of delusion and of the devil, whose teachings end in perdition and destruction. Tempt not Christ as they of old did. But how did they tempt him? Why, in loathing the manna, which was the type of his flesh and blood, which we are to eat of by believing. I say, tempt him not, lest you be destroyed by the serpents, by the gnawing guilt of sin; for, take away Christ, and sin remains, and there is no more sacrifice for sin: if so, thou wilt be destroyed by the destroyer (Num 21:5-7; 1 Cor 10:10). But again—
Second. Living by faith begets in the heart a son-like boldness and confidence to God-ward in all our gospel duties, under all our weaknesses, and under all our temptations. It is a blessed thing to be privileged with a holy boldness and confidence God-ward, that he is on our side, that he taketh part with us and that he will plead our cause 'with them that rise up against us' (2 Cor 2:14, 4:17,18; Gal 2:20). But this boldness faith helpeth us to do, and also manageth in our heart. This is that which made Paul always triumph and rejoice in God and the Lord Jesus (Phil 3:3; Rom 5:11). He lived the life of faith; for faith sets a man in the favour of God by Christ, and makes a man see that what befals him in this life, it shall, through the wisdom and mercy of God, not only prove for his forwarding to heaven, but to augment his glory when he comes there. This man now stands on high, he lives, he is rid of slavish fears and carking cares, and in all his straits he hath a God to go to! Thus David, when all things looked awry upon him, 'encouraged himself in the Lord his God' (1 Sam 30:6). Daniel also believed in his God, and knew that all his trouble, losses, and crosses, would be abundantly made up in his God (Dan 6:23). And David said, 'I had fainted unless I had believed' (Psa 27:13). Believing, therefore, is a great preservative against all such impediments, and makes us confident in our God, and with boldness to come into his presence, claiming privilege in what he is and hath (Jonah 3:4,5). For by faith, I say, he seeth his acceptance through the Beloved, and himself interested in the mercy of God, and riches of Christ, and glory in the world to come (Heb 10:22,23; Eph 1:4-7). This man can look upon all the dangers in hell and earth without paleness of countenance; he shall meditate terror with comfort, 'because he beholds the King in his beauty' (Isa 33:17,18). Again—
Third. Living by faith makes a man exercise patience and quietness under all his afflictions; for faith shows him that his best part is safe, that his soul is in God's special care and protection, purged from sin in the blood of Christ. Faith also shows him that after a little while he shall be in the full enjoyment of that which now he believes is coming: 'We, through the Spirit, wait for the hope of righteousness by faith' (Gal 5:5). Wherefore, upon this ground it is that James exhorteth the saints to whom he wrote, to patience, because they knew the harvest would in due time come (James 5:7-11). Faith lodgeth the soul with Christ: 'I know,' saith Paul, 'on whom I have believed,' and to whom I have committed my soul, 'and am persuaded,' I believe it, 'that he is able to keep that which I have committed unto him against that day'; therefore it were no shame to him to wear a chain for his name and sake (2 Tim 1:12). O! it is a blessed thing to see, I say, by the faith of the Lord Jesus, that we are embarked in the same ship with him; this will help us greatly 'both to hope and quietly wait for the salvation of the Lord' (Psa 46:1-6; Lam 3:26).
