Reader, let us seriously apply our hearts to the consideration of this great practical question. Let us look, seriously and honestly, to our ways. Let us, in truthfulness and uprightness of heart, inquire whether we are "unequally yoked together with unbelievers," on any ground, or for any object whatsoever. If so, let us give earnest heed to the words, "Come out from among them, and be ye separate, and touch not the unclean thing." It may be that the carrying out of this holy commandment will expose us to the charge of bigotry, narrowness, and intolerance; it may wear the aspect of pharisaic pride and self-complacency. We may be told, we are not to judge, or set ourselves up to be holier or better than other people. To all this line of argument we have the one simple, conclusive answer, namely, God's plain command. He tells us to be separate, to come out, to touch not the unclean; and all this in order to His receiving us, and acknowledging us as His sons and daughters. This ought to be quite sufficient for us. Let people think or say what they will of us,--let them call us what they please; God will settle the matter with them, sooner or later; our duty is to separate ourselves from unbelievers, if we would be received and owned of God. If believers are mixed up with unbelievers, how are they to be known or distinguished as the sons and daughters of the Lord Almighty? But we may perhaps be asked, How are we to know who are unbelievers? All profess to be Christians--all take the ground of belonging to Christ: we are not surrounded by ignorant heathen, or unbelieving Jews; how then are we to judge? It was plain enough in the early days of Christianity, when the apostle wrote his epistle to the assembly at Corinth--then the line of demarkation was as clear as a sunbeam; there were the three distinct classes--"the Jew, the Gentile, and the Church of God;" but now all is changed,--we live in a Christian land, under a Christian government, we are surrounded on all hands by Christians, and therefore 2 Corinthians vi. cannot apply to us; it was all very well when the Church was in its infancy, having just emerged from Judaism on the one hand and heathenism on the other, but to think of applying such a principle at this advanced stage of the Church's history, is wholly out of the question. To all who take this ground, we would put a very plain question,--Is it true that the Church has reached a stage of her history in which the New Testament is no longer her guide and authority? Have we got beyond the range of holy Scripture? If so, what are we to do? whither are we to turn for guidance? If we admit for a moment that 2 Corinthians vi. does not apply to Christians now, what warrant have we for appropriating to ourselves any portion of the New Testament?
