Does the reader feel any difficulty as to all this? It may be that he finds it hard, in the present broken and scattered condition of the members, to believe and confess the unbroken unity of the whole. He may feel disposed, perhaps, to limit the application of Ephesians iv. 4 to the day in which the apostle penned the words, when Christians were manifestly one, and when there was no such thing thought of as being a member of this church or a member of that church, because all believers were members of _the_ one Church.[23] [23] The unity of the Church may be compared to a chain thrown across a river; we see it at each side, but it dips in the middle. But though it dips, it is not broken; though we do not _see_ the union in the middle, we _believe_ it is there all the same. The Church was seen in its unity on the day of Pentecost, and it will be seen in its unity in the glory; and although we do not see it now, we nevertheless believe it most surely. And be it remembered that the unity of the body is a great practical, formative truth; and one very weighty practical deduction from it is that the state and walk of each member affect the whole body. "If one member suffer, all the members suffer with it." A member of what? Some local assembly? Nay; but a member of the body. We must not make the body of Christ a matter of geography. But, we may be asked, are we affected by what we do not see or know? Assuredly. Are we to limit the grand truth of the unity of the body, with all its practical consequences, to the measure of our personal knowledge and experience? Far be the thought. It is the presence of the Holy Ghost that unites the members of the body to the Head and to one another; and hence it is that the walk and ways of each affect all. Even in Israel's case, where it was not a corporate but a national unity, when Achan sinned, it was said, "Israel hath sinned;" and the whole congregation suffered a humiliating defeat on account of a sin of which they were ignorant. It is perfectly marvelous how little the Lord's people seem to understand the glorious truth of the unity of the body, and the practical consequences flowing from it. In reply, we must protest against the very idea of limiting the Word of God. What possible right have we to single out one clause from Ephesians iv. 4-6, and say it only applied to the days of the apostles? If one clause is to be so limited, why not all? Are there not still "one Spirit, one Lord, one faith, one baptism, one God and Father of all"? Will any question this? Surely not. Well, then, it follows that there is as surely one body as there is one Spirit, one Lord, one God. All are intimately bound up together, and you cannot touch one without touching all. We have no more right to deny the existence of the one body than we have to deny the existence of God, inasmuch as the self-same passage that declares to us the one declares to us the other also.
