(c) Union with Christ gives to the believer the legal standing and rights of Christ. As Christ's union with the race involves atonement, so the believer's union with Christ involves Justification. The believer is entitled to take for his own all that Christ is, and all that Christ has done; and this because he has within him that new life of humanity which suffered in Christ's death and rose from the grave in Christ's resurrection,—in other words, because he is virtually one person with the Redeemer. In Christ the believer is prophet, priest, and king.
Acts 13:39—“by him [lit.: ‘in him’ = in union with him] every one that believeth is justified”; Rom. 6:7, 8—“he that hath died is justified from sin ... we died with Christ”; 7:4—“dead to the law through the body of Christ”; 8:1—“no condemnation to them that are in Christ Jesus”; 17—“heirs of God, and joint-heirs with Christ”; 1 Cor. 1:30—“But of him ye are in Christ Jesus, who was made unto us wisdom from God, and righteousness[justification]”; 3:21, 23—“all things are yours ... and ye are Christ's”; 6:11—“ye were justified in the name of the Lord Jesus Christ, and in the Spirit of our God”; 2 Cor. 5:14—“we thus judge, that one died for all, therefore all died”; 21—“Him who knew no sin he made to be sin on our behalf; that we might become the righteousness [justification] of God in him” = God's justified persons, in union with Christ (see pages 760, 761).
Gal. 2:20—“I have been crucified with Christ; and it is no longer I that live, but Christ liveth in me”; Eph. 1:4, 6—“chose us in him ... to the praise of the glory of his grace, which he freely bestowed on us in the Beloved”; 2:5, 6—“even when we were dead through our trespasses, made us alive together with Christ ... made us to sit with him in the heavenly places, in Christ Jesus”; Phil. 3:8, 9—“that I may gain Christ, and be found in him, not having a righteousness of mine own, even that which is of the law, but that which is through faith in Christ, the righteousness which is from God by faith”; 2 Tim. 2:11—“Faithful is the saying: For if we died with him, we shall also live with him.” Prophet: Luke 12:12—“the Holy Spirit shall teach you in that very hour what ye ought to say”; 1 John 2:20—“ye have an anointing from the Holy One, and ye know all things.” Priest: 1 Pet. 2:5—“a holy priesthood, to offer up spiritual sacrifices, acceptable to God through Jesus Christ”; Rev. 20:6—“they shall be priests of God and of Christ”; 1 Pet. 2:9—“a royal priesthood.” King: Rev. 3:21—“He that overcometh, I will give to him to sit down with me in my throne”; 5:10—“madest them to be unto our God a kingdom and priests.”The connection of justification and union with Christ delivers the former from the charge of being a mechanical and arbitrary procedure. As Jonathan Edwards has said: “The justification of the believer is no other than his being admitted to communion in, or participation of, this head and surety of all believers.”
(d) Union with Christ secures to the believer the continuously transforming, assimilating power of Christ's life,—first, for the soul; secondly, for the body,—consecrating it in the present, and in the future raising it up in the likeness of Christ's glorified body. This continuous influence, so far as it is exerted in the present life, we call Sanctification, the human side or aspect of which is Perseverance.
For the soul: John 1:16—“of his fulness we all received, and grace for grace”—successive and increasing measures of grace, corresponding to the soul's successive and increasing needs; Rom. 8:10—“if Christ is in you, the body is dead because of sin; but the spirit is life because of righteousness”; [pg 806] 1 Cor. 15:45—“The last Adam became a life-giving spirit”; Phil. 2:5—“Have this mind in you, which was also in Christ Jesus”; 1 John 3:2—“if he shall be manifested, we shall be like him.” “Can Christ let the believer fall out of his hands? No, for the believer is his hands.”
For the body: 1 Cor. 6:17-20—“he that is joined unto the Lord is one spirit ... know ye not that your body is a temple of the Holy Spirit which is in you ... glorify God therefore in your body”; Thess. 5:23—“And the God of peace himself sanctify you wholly; and may your spirit and soul and body be preserved entire, without blame at the coming of our Lord Jesus Christ”; Rom. 8:11—“shall give life also to your mortal bodies through his Spirit that dwelleth in you”; 1 Cor. 15:49—“as we have borne the image of the earthy [man], we shall also bear the image of the heavenly [man]”; Phil. 3:20, 21—“For our citizenship is in heaven; from whence also we wait for a Savior, the Lord Jesus Christ: who shall fashion anew the body of our humiliation, that it may be conformed to the body of his glory, according to the working whereby he is able even to subject all things unto himself.”
Is there a physical miracle wrought for the drunkard in his regeneration? Mr. Moody says, Yes; Mr. Gough says, No. We prefer to say that the change is a spiritual one; but that the “expulsive power of a new affection” indirectly affects the body, so that old appetites sometimes disappear in a moment; and that often, in the course of years, great changes take place even in the believer's body. Tennyson, Idylls: “Have ye looked at Edyrn? Have ye seen how nobly changed? This work of his is great and wonderful; His very face with change of heart is changed.” “Christ in the soul fashions the germinal man into his own likeness,—this is the embryology of the new life. The cardinal error in religious life is the attempt to live without proper environment”(see Drummond, Natural Law in Spiritual World, 253-284). Human life from Adam does not stand the test,—only divine-human life in Christ can secure us from falling. This is the work of Christ, now that he has ascended and taken to himself his power, namely, to give his life more and more fully to the church, until it shall grow up in all things into him, the Head, and shall fitly express his glory to the world.
As the accomplished organist discloses unsuspected capabilities of his instrument, so Christ brings into activity all the latent powers of the human soul. “I was five years in the ministry,” said an American preacher, “before I realized that my Savior is alive.” Dr. R. W. Dale has left on record the almost unutterable feelings that stirred his soul when he first realized this truth; see Walker, The Spirit and the Incarnation, preface, v. Many have struggled in vain against sin until they have admitted Christ to their hearts,—then they could say: “this is the victory that hath overcome the world, even our faith”(1 John 5:4). “Go out, God will go in; Die thou, and let him live; Be not, and he will be; Wait, and he'll all things give.” The best way to get air out of a vessel is to pour water in. Only in Christ can we find our pardon, peace, purity, and power. He is “made unto us wisdom from God, and justification and sanctification, and redemption” (1 Cor. 1:30). A medical man says: “The only radical remedy for dipsomania is religiomania” (quoted in William James, Varieties of Religious Experience, 268). It is easy to break into an empty house; the spirit cast out returns, finds the house empty, brings seven others, and “the last state of that man becometh worse than the first” (Mat. 12:45). There is no safety in simply expelling sin; we need also to bring in Christ; in fact only he can enable us to expel not only actual sin but the love of it.
Alexander McLaren: “If we are ‘in Christ,’ we are like a diver in his crystal bell, and have a solid though invisible wall around us, which keeps all sea-monsters off us, and communicates with the upper air, whence we draw the breath of calm life and can work in security though in the ocean depths.” John Caird, Fund. Ideas, 2:98—“How do we know that the life of God has not departed from nature? Because every spring we witness the annual miracle of nature's revival, every summer and autumn the waving corn. How do we know that Christ has not departed from the world? Because he imparts to the soul that trusts him a power, a purity, a peace, which are beyond all that nature can give.”
(e) Union with Christ brings about a fellowship of Christ with the believer,—Christ takes part in all the labors, temptations, and sufferings of his people; a fellowship of the believer with Christ,—so that Christ's whole experience on earth is in some measure reproduced in him; a fellowship of all believers with one another,—furnishing a basis for the spiritual unity of Christ's people on earth, and for the eternal communion of heaven. The doctrine of Union with Christ is therefore the indispensable preparation for Ecclesiology, and for Eschatology.
