Help Second, Labour to see the emptiness, shortness, and the pollution that cleaveth to a man's own righteousness. This also must in some measure be known, before a man can know the nature of the love of Christ. They that see nothing of the loathsomeness of man's best things, will think, that the love of Christ is of that nature as to be procured, or won, obtained or purchased by man's good deeds. And although so much gospel light is broke forth as to stop men's mouths from saying this, yet 'tis nothing else but sound conviction of the vileness of man's righteousness, that will enable men to see that the love of Christ is of that nature, as to save a man without it; as to see that it is of that nature as to justify him without it: I say, without it, or not at all. There is shortness, there is hypocrisy, there is a desire of vain glory, there is pride, there is presumption in man's own righteousness: nor can it be without these wickednesses, when men know not the nature of the love of Christ. Now these defile it, and make it abominable. Yea, if there were no imperfection in it, but that which I first did mention, to wit, shortness; how could it cover the nakedness of him that hath it, or obtain for the man, in whole or in part, that Christ should love, and have respect unto him.
Occasions many thou hast given thee to see the emptiness of man's own righteousness, but all will not do unless thou hast help from heaven: wherefore thy wisdom will be, if thou canst tell where to find it, to lie in the way of God, that when he comes to visit the men that wait upon him in the means of his own appointing, thou mayest be there; if perhaps he may cast an eye of pity upon thy desolate soul, and make thee see the things above mentioned. That thou mayest know the nature of the love of Christ.
Help Third, If thou wouldest know the nature of this love, be much in acquainting of thy soul with the nature of the law, and the nature of the gospel (Gal 3:21). The which though they are not diametrically opposite one to another, yet do propound things so differently to man, that if he knows not where, when, and how to take them, 'tis impossible but that he should confound them, and in confounding of them, lose his own soul (Rom 9:31,32). The law is a servant, both first and last, to the gospel (Rom 10:3,4): when therefore it is made a Lord, it destroyeth: and then to be sure it is made a Lord and Saviour of, when its dictates and commands are depended upon for life.
Thy wisdom therefore will be to study these things distinctly, and thoroughly; for so far as thou art ignorant of the true knowledge of the nature of these, so far thou art ignorant of the true knowledge of the nature of the love of Christ. Read Paul to the Galatians, that epistle was indicted by the Holy Ghost, on purpose to direct the soul, in, and about this very thing.
Help Fourth, The right knowledge of the nature of the love of Christ, is obtained, and retained, by keeping of these two doctrines at an everlasting distance as to the conscience; to wit, not suffering the law to rule but over my outward man, not suffering the gospel to be removed one hair's breadth from my conscience. When Christ dwells in my heart by faith (Eph 3:17), and the moral law dwells in my members (Col 3:5), the one to keep up peace with God, the other to keep my conversation in a good decorum: then am I right, and not till then.
But this will not be done without much experience, diligence, and delight in Christ. For there is nothing that Satan more desireth, than that the law may abide in the conscience of an awakened Christian, and there take up the place of Christ, and faith; for he knows if this may be obtained, the vail is presently drawn over the face of the soul, and the heart darkened as to the knowledge of Christ; and being darkened, the man is driven into despair of mercy, or is put upon it to work for life (2 Cor 3:13-15). There is therefore, as I say, much diligence required of him that will keep these two in their places assigned them of God. I say much diligent study of the word, diligent prayer; with diligence to walk with God in the world. But we will pass this, and come to the second head.
Secondly, As the love of Christ may be known in the nature of it, so it may be known in many degrees of it. That which is knowable, admits of degrees of knowledge: the love of Christ is knowable. Again, that which is not possible to be known to the utmost, is to be known, we know not how much; and therefore they that seek to know it, should never be contented or satisfied to what degree of the knowledge of it soever they attain; but still should be reaching forward, because there is more to be known of it before them. "Brethren," said Paul, "I count not myself to have apprehended, (that is to the utmost) but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before, I press towards the mark for the prize of the high calling of God in Christ Jesus" (Phil 3:13,14). I might here discourse of many things, since I am upon this head of reaching after the knowledge of the love of Christ in many of the degrees of it. But I shall content myself with few.
1. He that would know the love of Christ in several degrees of it, must begin at his person, for in him dwells all the treasures of wisdom and knowledge. Nay, more; In him "are hid all the treasures of wisdom and knowledge" (Col 2:3). In him, that is, in his person: For, for the godhead of Christ, and our nature to be united in one person, is the highest mystery, and the first appearance of the love of Christ by himself, to the world (1 Tim 3:16). Here I say, lie hid the treasures of wisdom, and here, to the world, springs forth the riches of his love (John 1:14). That the eternal word, for the salvation of sinners, should come down from heaven and be made flesh, is an act of such condescension, a discovery of such love, that can never to the full be found out. Only here we may see, love in him was deep, was broad, was long, and high: let us therefore first begin here to learn to know the love of Christ, in the high degrees thereof.
(1.) Here, in the first place, we perceive love, in that the human nature, the nature of man, not of angels, is taken into union with God. Who so could consider this, as it is possible for it to be considered, would stand amazed till he died with wonder. By this very act of the heavenly wisdom, we have an inconceivable pledge of the love of Christ to man: for in that he hath taken into union with himself our nature, what doth it signify, but that he intendeth to take into union with himself our person. For, for this very purpose did he assume our nature. Wherefore we read that in the flesh he took upon him, in that flesh, he died for us, the just for the unjust, that he might bring us to God (1 Peter 3:18).
(2.) As he was made flesh, so as was said afore, he became a public or common person for us: and hereby is perceived another degree of his love; undertaking to do for his, what was not possible they should do for themselves, perfecting of righteousness to the very end of the law, and doing for us, to the reconciling of us unto his Father, and himself (Rom 10:3,4, 3:24).
