Let all missionaries remember this. They may rest assured it will not clip their wings, or cripple their energies; it will only guide their movements, by giving them a divine aim and object. Of what possible use can it be for a man to propose as the end of his labors something wholly different from that which is before the mind of God? Ought not a servant to seek to do his master's will? Can he expect to please his master by pursuing other than his clearly expressed object? It is blessedly true, that all the earth shall yet be filled with the knowledge of the Lord as the waters cover the sea. There is no question as to this. All Scripture bears witness to it. To quote the passages would literally fill a volume. All Christians are agreed on this point, and hence there is no need to adduce evidence. But the question is, how is this grand and glorious result to be brought about? Is it the purpose of God to use the professing Church as His agent, or a preached gospel as His instrument, in the conversion of the world? Scripture says No; with a clearness which ought to sweep away every doubt. And here let it be distinctly understood that we delight in all true missionary effort. We heartily wish God's speed to every true missionary--to every one who has left home, and kindred, and friends, and all the comforts and privileges of civilized life, in order to carry the glad tidings of salvation into the dark places of the earth. We desire to render hearty thanks to God for all that has been accomplished in the fields of foreign missions; though we cannot approve some modes by which the work is carried on. We consider there is a lack of simple faith in God, and of subjection to the authority of Christ, and the guidance of the Holy Ghost. There is too much of human machinery, and looking to the world for aid. But all this is not our present object. The point with which we are occupied in this brief paper is this--_will_ God make use of the professing Church to convert the nations? We ask not, _has_ He done so? for, were we to put the question thus, we could only receive an unqualified negative; for the professing Church has been at work for eighteen long centuries; and what is the result? Let the reader take a glance at a missionary map, and he will see in a moment. Look at those large patches of black, designed to set forth the dismal regions over which heathenism bears sway. Look at the red, the green, the yellow, setting forth popery, the Greek church, and Mohammedanism. And where is--we say not true Christianity, but even nominal Protestantism? That is indicated by those spots of blue which, if all put together, make but a small fraction indeed. And as to what even this Protestantism is we need not now stop to inquire.
