Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour.--1 Peter 5:8
Satan is now using every device in this sealing time to keep the minds of God's people from the present truth and to cause them to waver. I saw a covering that God was drawing over His people to protect them in the time of trouble; and every soul that was decided on the truth and was pure in heart was to be covered with the covering of the Almighty.
Satan knew this, and he was at work in mighty power to keep the minds of as many people as he possibly could wavering and unsettled on the truth. I saw that the mysterious knocking in New York and other places was the power of Satan, and that such things would be more and more common, clothed in a religious garb so as to lull the deceived to greater security and to draw the minds of God's people, if possible, to those things and cause them to doubt the teachings and power of the Holy Ghost.
I saw that Satan was working through agents in a number of ways. He was at work through ministers who have rejected the truth and are given over to strong delusions to believe a lie that they might be damned. While they were preaching or praying, some would fall prostrate and helpless, not by the power of the Holy Ghost, but by the power of Satan breathed upon these agents, and through them to the people.
While preaching, praying, or conversing, some professed Adventists who had rejected present truth used mesmerism to gain adherents, and the people would rejoice in this influence, for they thought it was the Holy Ghost. Some even that used it were so far in the darkness and deception of the devil that they thought it was the power of God, given them to exercise. They had made God altogether such a one as themselves and had valued His power as a thing of nought. (Early Writings, 43-44)
REFLECTION: The temptations of Satan are greater now than ever before, for he knew that his time is short and that very soon every case will be decided, either for life or for death....The Lord has shown me that His grace is sufficient for all our trials; and although they are greater than ever before, yet if we trust wholly in God, we can overcome every temptation and through His grace come off victorious. (Early Writings, 46)
