Unity a practical reality
According to the New Testament standard, unity of believers is more than an invisible, intangible, spiritual fellowship. They are "members one of another" as well as members of Christ. That unity was designed to be visible and to form a convincing sign to the world of the mighty power of Christ. This stands out prominently in that notable prayer of our Lord recorded in John 17, which was uttered on the most solemn night of his earthly life. First he prayed for his immediate disciples, then for all believers, in these words: "Neither pray I for these [twelve] alone, but for them also which shall believe on me through their word; THAT THEY ALL MAY BE ONE; as thou, Father, art in me, and I in thee, that they also may be one in us: THAT THE WORLD MAY BELIEVE that thou hast sent me" (verses 20, 21).
Such unity is a real standard. It will convince the world. The practical force of this last scripture can not be lessened by reference to those other words of Jesus, "By this shall all men know that ye are my disciples, if ye have love one for another" (John 13: 35), for Jesus taught the inseparable nature of love and unity. Love, as an inward affection, produces deeds and results, and is measured thereby. Jesus said, "If a man love me, he will keep my words; and my Father will love him, and we will come unto him, and make our abode with him" (John 14: 23). And just as love to God invariably produces union with God, so also true love to man will result in unity. "My little children, let us not love in word, neither in tongue; but in deed and in truth" (1 John 3:18). Carnal divisions can not exist where true love reigns.
Christ died for unity
For this visible unity Christ prayed—"That they all may be one,... that the world may believe." More than this, he died that unity might be effected. John 11:52 clearly shows that one purpose of Christ's death was that "he should gather together in one the children of God that were scattered abroad." Therefore unity of believers is a sacred truth resting on the solid basis of the atonement. That this unity is more than that general union resulting from the personal attachment of separate individuals to Christ as a common center, is proved by the fact that it is designed to gather together in one the scattered children of God. Jesus himself said, "Other sheep I have [Gentiles], which are not of this [Jewish] fold: them also I must bring, and they shall hear my voice; and THERE SHALL BE ONE FOLD [flock] AND ONE SHEPHERD" (John 10:16).
Jew and Gentile united
Broadly speaking, there were at that time but two classified divisions of men—Jews and Gentiles. Jesus predicted that his sheep from both sections should be brought together into one flock. In the second chapter of Ephesians, Paul tells us how this was accomplished. Although "in times past" the Gentiles were "strangers from the covenants of promise, having no hope and without God in the world," in Christ they were "made nigh by the blood." "For he is our peace, who hath made both [Jews and Gentiles] ONE, and hath broken down the middle wall of partition between us ... that he might reconcile both unto God in one body by the cross" (verses 12-16). Since this glorious reunion through Christ, the Gentiles "are no more strangers and foreigners, but fellow citizens with the saints, and of the household of God." They also "are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner-stone ... in whom ye also are builded together for an habitation of God through the Spirit" (verses 19-22).
On account of the high standard of unity set forth in his epistles, Paul has been branded an idealist. But what shall we say of Christ who prayed for such visible unity and died for it? An idealist is one who forms picturesque fancies, one given to romantic expectations impossible of accomplishment. The idealist usually has but few practical results. But Paul accomplished things. He broke away from his Jewish prejudices, which brought down upon his head the wrath of his fellows. He went into the synagogs of the Jews and brought out those who were willing to become disciples of Jesus. To build up the work of the Lord he labored night and day with tears; he laid broad and deep the very foundations of the Christian faith in heathen lands. Within a very few years he established Christian churches in four provinces of the Roman Empire—churches in which Jew and Gentile met together in common fellowship, in one body. If this is idealism, Lord, give us many more such idealists.
