“God will test the fidelity of His people. Many of the mistakes that are made by the professed servants of God are in consequence of their self-love, their desire for approval, their thirst for popularity. Blinded in this manner, they do not realize that they are elements of darkness rather than of light. “Come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you, and will be a Father unto you, and ye shall be My sons and daughters, saith the Lord Almighty.” These are the conditions upon which we may be acknowledged as the sons of God—separation from the world, and renunciation of those things which delude, and fascinate, and ensnare.
The apostle Paul declares that it is impossible for the children of God to unite with worldlings: “Be ye not unequally yoked together with unbelievers.” This does not refer to marriage alone; any intimate relation of confidence and copartnership with those who have no love for God or the truth is a snare.
The apostle continues: “For what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? and what concord hath Christ with Belial? or what part hath he that believeth with an infidel? and what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said: I will dwell in them, and walk in them; and I will be their God, and they shall be My people.” In consideration of these facts, he exclaims: “Wherefore come out from among them, and be ye separate.” “Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.”
If we comply with the conditions, the Lord will fulfill to us His promises. But there is a work for us to do which we should in no wise neglect. In the strength of Jesus we can perform it aright. We may press ever onward and upward, constantly growing in grace and in a knowledge of the truth.
The children of the light and of the day are not to gather about them the shades of night and darkness which encompass the workers of iniquity. On the contrary, they are to stand faithfully at their post of duty as light bearers, gathering light from God to shed upon those in darkness. The Lord requires His people to maintain their integrity, touching not—that is, imitating not—the practices of the ungodly.” 5T 12.4 – 5T 13.4
