I have been shown that evil angels in the form of believers will work in our ranks to bring in a strong spirit of unbelief. Let not even this discourage you, but bring a true heart to the help of the Lord against the powers of satanic agencies. These powers of evil will assemble in our meetings, not to receive a blessing, but to counterwork the influences of the Spirit of God. Take up no remark that they may make, but repeat the rich promises of God, which are yea and amen in Christ Jesus. We are never to catch up the words that human lips may speak to confirm the evil angels in their work, but we should repeat the words of Christ. Christ was the Instructor in the assemblies of these angels before they fell from their high estate.We have great and solemn truths to give to the world, and they are to be proclaimed in no hesitating, limping style. The trumpet is to give a certain sound. Some will come to hear the strange message out of curiosity; others with a longing to receive true knowledge, asking the question, “What shall I do that I may inherit eternal life?”
Thus men came to Christ. And mingling with His hearers were [evil] angels in the form of men, making their suggestions, criticizing, misapplying, and misinterpreting the Saviour's words...
In this time evil angels in the form of men will talk with those who know the truth. They will misinterpret and misconstrue the statements of the messengers of God...
Have Seventh-day Adventists forgotten the warning given in the sixth chapter of Ephesians? We are engaged in a warfare against the hosts of darkness. Unless we follow our Leader closely, Satan will obtain the victory over us.3SM 410,411
A positive balance -
The heavenly sentinels, faithful to their trust, continue their watch…In all ages, God has wrought through holy angels for the succor and deliverance of His people. Celestial beings have taken an active part in the affairs of men. They have appeared clothed in garments that shone as the lightning; they have come as men in the garb of wayfarers. Angels have appeared in human form to men of God. They have rested, as if weary, under the oaks at noon. They have accepted the hospitalities of human homes. They have acted as guides to benighted travelers. They have, with their own hands, kindled the fires at the altar. They have opened prison doors and set free the servants of the Lord. Clothed with the panoply of heaven, they came to roll away the stone from the Saviour's tomb.
In the form of men, angels are often in the assemblies of the righteous; and they visit the assemblies of the wicked, as they went to Sodom, to make a record of their deeds, to determine whether they have passed the boundary of God's forbearance. The Lord delights in mercy; and for the sake of a few who really serve Him, He restrains calamities and prolongs the tranquillity of multitudes. Little do sinners against God realize that they are indebted for their own lives to the faithful few whom they delight to ridicule and oppress.
Though the rulers of this world know it not, yet often in their councils angels have been spokesmen. Human eyes have looked upon them; human ears have listened to their appeals; human lips have opposed their suggestions and ridiculed their counsels; human hands have met them with insult and abuse. In the council hall and the court of justice these heavenly messengers have shown an intimate acquaintance with human history; they have proved themselves better able to plead the cause of the oppressed than were their ablest and most eloquent defenders. They have defeated purposes and arrested evils that would have greatly retarded the work of God and would have caused great suffering to His people. In the hour of peril and distress “the angel of the Lord encampeth round about them that fear Him, and delivereth them.” GC 631, 632
