III. The Church represents Christian fellowship.--(_a_) It keeps up the idea of brotherhood in the world. It brings people of different ranks and classes together, and that under most favorable circumstances. Whatever a man is in the world, in the Church he is made to feel that in the eye of God he is a member of one family, having the same weaknesses, the same sorrows, the same needs, the same destiny before him as those around him. In the Church "the rich and poor meet together" in equality before the same God, who is the Maker of them all. (_b_) But especially in its worship is the Church a common bond between _believers_. On one day of the week men of all nations, kindreds, peoples and tongues, a multitude whom no man can number, unite in spirit together. Their prayers and praises ascend in unison to the Throne of Grace. They enter into the "communion of saints." They belong to one holy fellowship. (_c_) At the table of the Lord they take their places as partakers of one life--as one in Christ. "The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ? For we being many are all partakers of that one bread." (1 Cor. x. 16, 17.) IV. The Church represents Christian Work.--It is not merely a society for instruction or for the cultivation of devout feelings. It is an aggressive society. Every congregation of believers is a branch of the great army which is warring against the kingdom of darkness. Every individual is called upon to be a "fellow-laborer with Christ," and not merely to work out his own salvation, but to work for the salvation of others. The motto of every true Christian Church should be, "Work for everybody, and everybody at work." Those who may be able to do little as isolated individuals may do much by combining their efforts with those of others. The Church gives them the power and the opportunity. We may now glance at some of the special duties incumbent upon those who are connected with the Church, and particularly upon young men.
