We need to be anchored in Christ, rooted and grounded in the faith. Satan works through agents. He selects those who have not been drinking of the living waters, whose souls are athirst for something new and strange, and who are ever ready to drink at any fountain that may present itself. Voices will be heard, saying, “Lo, here is Christ,” or “Lo, there;” but we must believe them not. We have unmistakable evidence of the voice of the True Shepherd, and He is calling upon us to follow Him. He says, “I have kept my Father’s commandments.” He leads His sheep in the path of humble obedience to the law of God, but He never encourages them in the transgression of that law.
 “The voice of a stranger” is the voice of one who neither respects nor obeys God’s holy, just, and good law. Many make great pretensions to holiness, and boast of the wonders they perform in healing the sick, when they do not regard this great standard of righteousness. But through whose power are these cures wrought? Are the eyes of either party opened to their transgressions of the law? and do they take their stand as humble, obedient children, ready to obey all of God’s requirements? John testifies of the professed children of God: “He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.”
 None need be deceived. The law of God is as sacred as His throne, and by it every man who cometh into the world is to be judged. There is no other standard by which to test character. “If they speak not according to this word, it is because there is no light in them.” Now, shall the case be decided according to the Word of God, or shall man’s pretensions be credited? Says Christ, “By their fruits ye shall know them.” If those through whom cures are performed, are disposed, on account of these manifestations, to excuse their neglect of the law of God, and continue in disobedience, though they have power to any and every extent, it does not follow that they have the great power of God. On the contrary, it is the miracle-working power of the great deceiver. He is a transgressor of the moral law, and employs every device that he can master to blind men to its true character. We are warned that in the last days he will work with signs and lying wonders. And he will continue these wonders until the close of probation that he may point to them as evidence that he is an angel of light and not of darkness.
 Brethren, we must beware of the pretended holiness that permits transgression of the law of God. Those cannot be sanctified who trample that law under their feet, and judge themselves by a standard of their own devising (The Review and Herald, November 17, 1885).
