When Jesus leaves the most holy, His restraining Spirit is withdrawn from rulers and people. They are left to the control of evil angels. Then such laws will be made by the counsel and direction of Satan, that unless time should be very short, no flesh could be saved.49Testimonies for the Church 1:204.
I saw that the four angels would hold the four winds until Jesus’ work was done in the sanctuary, and then will come the seven last plagues. These plagues enraged the wicked against the righteous; they thought that we had brought the judgments of God upon them, and that if they could rid the earth of us, the plagues would then be stayed. A decree went forth to slay the saints, which caused them to cry day and night for deliverance. This was the time of Jacob's trouble.50Early Writings, 36-37.
I saw the leading men of the earth consulting together, and Satan and his angels busy around them. I saw a writing, copies of which were scattered in different parts of the land, giving orders that unless the saints should yield their peculiar faith, give up the Sabbath, and observe the first day of the week, the people were at liberty after a certain time to put them to death.51Early Writings, 282-283.
Though a general decree has fixed the time when commandment keepers may be put to death, their enemies will in some cases anticipate the decree, and before the time specified, will endeavor to take their lives. But none can pass the mighty guardians stationed about every faithful soul. Some are assailed in their flight from the cities and villages; but the swords raised against them break and fall powerless as a straw. Others are defended by angels in the form of men of war.52The Great Controversy, 631.
Could men see with heavenly vision, they would behold companies of angels that excel in strength stationed about those who have kept the word of Christ's patience. With sympathizing tenderness, angels have witnessed their distress and have heard their prayers. They are waiting the word of their Commander to snatch them from their peril. But they must wait yet a little longer. The people of God must drink of the cup and be baptized with the baptism.53The Great Controversy, 630-631. Mar 268
There is nothing more calculated to strengthen the intellect than the study of the Scriptures. No other book is so potent to elevate the thoughts, to give vigor to the faculties, as the broad, ennobling truths of the Bible. If God's word were studied as it should be, men would have a breadth of mind, a nobility of character, and a stability of purpose rarely seen in these times. SC 90
And he had power to ... cause that as many as would not worship the image of the beast should be killed. Revelation 13:15. KJV
