So what is this communion with Christ? How does it come about? Does the life of a believer look differently because of this grace that has been bestowed on them? John Owen has stated the following:
True believers "hold communion with the Lord Christ. And wherein and how they do it, shall now be declared.
They continually eye the Lord Jesus as the great Joseph, that hath the disposal of all the granaries of the kingdom of heaven committed unto him; as one in whom it hath pleased the Father to gather all things unto a head, Eph. i. 10, that from him all things might be dispensed unto them. All treasures, all fulness, the Spirit not by measure, are in him. And this fulness in this Joseph, in reference to their condition, they eye in these three particulars:—
(1.) In the preparation unto the dispensation mentioned, in the expiating, purging, purifying efficacy of his blood. It was a sacrifice not only of atonement, as offered, but also of purification, as poured out. This the apostle eminently sets forth, Heb. ix. 13, 14, “For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: how much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?” This blood of his is that which answers all typical institutions for carnal purification; and therefore hath a spiritually-purifying, cleansing, sanctifying virtue in itself, as offered and poured out. Hence it is called, “A fountain for sin and for uncleanness,” Zech. xiii. 1; that is, for their washing and taking away; — “A fountain opened;” ready prepared, virtuous, efficacious in itself, before any be put into it; because poured out, instituted, appointed to that purpose.
The saints see that in themselves they are still exceedingly defiled; and, indeed, to have a sight of the defilements of sin is a more spiritual discovery than to have only a sense of the guilt of sin. This follows every conviction, and is commensurate unto it; that, usually only such as reveal the purity and holiness of God and all his ways. Hereupon they cry with shame, within themselves, “Unclean, unclean,” — unclean in their natures, unclean in their persons, unclean in their conversations; all rolled in the blood of their defilements; their hearts by nature a very sink, and their lives a dung hill. Ezek. xvi. 4, 6, John iii. 3, 5, Rev. xxi. 27; Hab. i. 13. They know, also, that no unclean thing shall enter into the kingdom of God, or have place in the new Jerusalem; that God is of purer eyes than to behold iniquity. They cannot endure to look on themselves; and how shall they dare to appear in his presence? What remedies shall they now use? “Though they wash themselves with nitre, and take them much soap, yet their iniquity will continue marked,” Jer. ii. 22. Wherewith, then, shall they come before the Lord?
For the removal of this, I say, they look, in the first place, to the purifying virtue of the blood of Christ, which is able to cleanse them from all their sins, 1 John i. 7; being the spring from whence floweth all the purifying virtue, which in the issue will take away all their spots and stains, “make them holy and without blemish, and in the end present them glorious unto himself,” Eph. v. 26, 27. This they dwell upon with thoughts of faith; they roll it in their minds and spirits. Here faith obtains new life, new vigour, when a sense of vileness hath even overwhelmed it. Here is a fountain opened: draw nigh, and see its beauty, purity, and efficacy. Here is a foundation laid of that work whose accomplishment we long for. One moment’s communion with Christ by faith herein is more effectual to the purging of the soul, to the increasing of grace, than the utmost self-endeavours of a thousand ages.
(2.) They eye the blood of Christ as the blood of sprinkling. Coming to “Jesus, the mediator of the new covenant,” they come to the “blood of sprinkling,” Heb. xii. 24. The eyeing of the blood of Christ as shed will not of itself take away pollution. There is not only a “shedding of blood,” without which there is no remission, Heb. ix. 22; but there is also a “sprinkling of blood,” without which there is no actual purification. This the apostle largely describes, Heb. ix. 19, “When Moses,” saith he, “had spoken every precept to all the people according to the law, he took the blood of calves and of goats, with water, and scarlet wool, and hyssop, and sprinkled both the book and all the people, saying, This is the blood of the testament which God hath enjoined unto you. Moreover he sprinkled likewise with blood both the tabernacle, and all the vessels of the ministry. And almost all things are by the law purged with blood. It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these,” verses 19–23. He had formerly compared the blood of Christ to the blood of sacrifices, as offered, in respect of the impetration and the purchase it made; now he doth it unto that blood as sprinkled, in respect of its application unto purification and holiness. And he tells us how this sprinkling was performed: it was by dipping hyssop in the blood of the sacrifice, and so dashing it out upon the things and persons to be purified; as the institution also was with the paschal lamb, Exod. xii. 7. Hence, David, in a sense of the pollution of sin, prays that he may be “purged with hyssop,” Ps. li. 7. For that this peculiarly respected the uncleanness and defilement of sin, is evident, because there is no mention made, in the institution of any sacrifice (after that of the lamb before mentioned), of sprinkling blood with hyssop, but only in those which respected purification of uncleanness; as in the case of leprosy, Lev. xiv. 6; and all other defilements, Numb. xix. 18: which latter, indeed, is not of blood, but of the water of separation; this also being eminently typical of the blood of Christ, which is the fountain for separation for uncleanness, Zech. xiii. 1. Now, this bunch of hyssop, wherein the blood of purification was prepared for the sprinkling of the unclean, is (unto us) the free promises of Christ. The cleansing virtue of the blood of Christ lies in the promises, as the blood of sacrifices in the hyssop, ready to pass out unto them that draw nigh thereunto. Therefore the apostle argueth from receiving of the promise unto universal holiness and purity: “Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God,” 2 Cor. vii. 1. This, then, the saints do:— they eye the blood of Christ as it is in the promise, ready to issue out upon the soul, for the purification thereof; and thence is purging and cleansing virtue to be communicated unto them, and by the blood of Christ are they to be purged from all their sins, 1 John i. 7. Thus far, as it were, this purifying blood, thus prepared and made ready, is at some distance to the soul. Though it be shed to this purpose, that it might purge, cleanse, and sanctify, though it be taken up with the bunch of hyssop in the promises, yet the soul may not partake of it. Wherefore, —
(3.) They look upon him as, in his own Spirit, he is the only dispenser of the Spirit and of all grace of sanctification and holiness. They consider that upon his intercession it is granted to him that he shall make effectual all the fruits of his purchase, to the sanctification, the purifying and making glorious in holiness, of his whole people. They know that this is actually to be accomplished by the Spirit, according to the innumerable promises given to that purpose. He is to sprinkle that blood upon their souls; he is to create the holiness in them that they long after; he is to be himself in them a well of water springing up to everlasting life. In this state they look to Jesus: here faith fixes itself, in expectation of his giving out the Spirit for all these ends and purposes; mixing the promises with faith, and so becoming actual partaker of all this grace. This is their way, this their communion with Christ; this is the life of faith, as to grace and holiness. Blessed is the soul that is exercised therein: “He shall be as a tree planted by the waters, and that spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit,” Jer. xvii. 8. Convinced persons who know not Christ, nor the fellowship of his sufferings, would spin a holiness out of their own bowels; they would work it out in their own strength. They begin it with Rom. x. 1–4 trying endeavours; and follow it with vows, duties, resolutions, engagements, sweating at it all the day long. Thus they continue for a season, — their hypocrisy, for the most part, ending in apostasy. The saints of God do, in the very entrance of their walking with him, reckon upon it that they have a threefold want:—
[1.] Of the Spirit of holiness to dwell in them.
[2.] Of a habit of holiness to be infused into them.
[3.] Of actual assistance to work all their works for them; and that if these should continue to be wanting, they can never, with all their might, power, and endeavours, perform any one act of holiness before the Lord. They know that of themselves they have no sufficiency, — that John xv. 5 without Christ they can do nothing: therefore they look to him, who is intrusted with a fulness of all these in their behalf; and thereupon by faith derive from him an increase of that whereof they stand in need.
Thus, I say, have the saints communion with Christ, as to their sanctification and holiness. From him do they receive the Spirit to dwell in them; from him the new principle of life, which is the root of all their obedience; from him have they actual assistance for every duty they are called unto. In waiting for, expectation and receiving of these blessings, on the accounts before mentioned, do they spend their lives and time with him. In vain is help looked for from other mountains; in vain do men spend their strength in following after righteousness, if this be wanting. Fix thy soul here; thou shalt not tarry until thou be ashamed. This is the way, the only way, to obtain full, effectual manifestations of the Spirit’s dwelling in us; to have our hearts purified, our consciences purged, our sins mortified, our graces increased, our souls made humble, holy, zealous, believing, — like to him; to have our lives fruitful, our deaths comfortable. Let us herein abide, eyeing Christ by faith, to attain that measure of conformity to him which is allotted unto us in this world, that when we shall see him as he is, we may be like unto him."
Christ is our all in all - may His name be praised forever. Amen.
