Test everything before it shall be presented to the flock of God.... In messages that profess to be from Heaven, expressions will be made that are misleading, and if the influence of these things be accepted, it will lead to exaggerated movements, plans, and devising that will bring in the very things that Satan would have current—a strange spirit, an unclean spirit, under the garments of sanctity; a strong spirit to overbear everything. Fanaticism will come in, and will so mingle and interweave itself with the workings of the Spirit of God, that many will accept it all as from God, and will be deceived and misled thereby. 3SM 403.1
There are strong statements often made by our brethren who bear the message of mercy and warning to our world, that would better be repressed.... Let not one word be expressed to stir up the spirit of retaliation in opposers of the truth. Let nothing be done to arouse the dragonlike spirit, for it will reveal itself soon enough, and in all its dragon character, against those who keep the commandments of God and have the faith of Jesus.... 3SM 403.2
Confronted by Our Carelessly Spoken Words—The time will come when we shall be called to stand before Kings and rulers, magistrates and powers, in vindication of the truth. Then it will be a surprise to those witnesses to learn that their positions, their words, the very expressions made in a careless manner or thoughtless way, when attacking error or advancing truth—expressions that they had not thought would be remembered—will be reproduced, and they will be confronted with them, and their enemies will have the advantage, putting their own construction on these words that were spoken unadvisedly.... 3SM 403.3
How Satan Will Work to Deceive—Many things intended to deceive us will come, bearing some of the marks of truth. Just as soon as these shall be set forth as the great power of God, Satan is all ready to weave in that which he has prepared to lead souls from the truth for this time. 3SM 404.1
Some will accept and promulgate the error, and when the reproof comes that will place matters in the true light, those who have had little experience and who are ignorant of the oft-repeated workings of Satan, will cast away with the rubbish of error that which has been before them as truth. Thus the light and warnings which God gives for this time will be made of no effect.... 3SM 404.2
False Messages Will Be Charged Upon Ellen White—Every conceivable message is coming to counterfeit the work of God, and always bearing the inscription of truth upon its banner. And those who are prepared for anything new and sensational, will handle these things in such a manner that our enemies will charge all that is inconsistent and overdone upon Mrs. E. G. White, the prophetess.... 3SM 404.3
There will be counterfeit messages coming from persons in all directions. One after another will rise up, appearing to be inspired, when they have not the inspiration of heaven, but are under the deception of the enemy. All who receive their messages will be led astray. Then let us walk carefully, and not open wide the door for the enemy to enter through impressions, dreams, and visions. God help us to look in faith to Jesus, and be guided by the words He has spoken.—Letter 66, 1894. 3SM 404.4
