"Be ye not unequally yoked together with unbelievers; for what fellowship hath righteausiess with unrighteousness? and what communion hath light with darkness?" (2 Corinthians 6:14-18)

This passage gives utterance to a Divine exhortation for those belonging to Christ to hold aloof from all intimate associations with the ungodly. It expressly forbids them entering into alliances with the unconverted. It definitely prohibits the children of God walking arm-in-arm with the world. It is an admonition applying to every phase and department of our lives-religious, domestic, social, commercial. And never, perhaps, was there a time when it more needed pressing on Christians than now. The days in which we are living are marked by the spirit of compromise. On every side we behold unholy mixtures, ungodly alliances, unequal yokes. Many professing Christians appear to be trying to see how near to the world they can walk and still go to Heaven.

"Be ye not unequally yoked together." We are fully persuaded that it is disregard of this commandment, for command it is, which is largely responsible for the low state which now obtains so generally among Christians, both individually and corporately. No wonder the spiritual pulse of many churches beats so feebly. No wonder prayer-meetings are so thinly attended; Christians who are unequally yoked have no heart for prayer. Disobedience at this point is a certain preventative to real and whole-hearted devotion to Christ. No one can be an unshackled follower of the Lord Jesus who is, in any way, "yoked" to His enemies, (the world and all it offers). He may be a truly saved person, but the testimony of his life, the witness his walk, will not honor and glorify Christ.
