“And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree. And I saw another angel ascending from the east, having the seal of the living God: and he cried with a loud voice to the four angels, to whom it was given to hurt the earth and the sea, Saying, Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads. ” (Revelation 7:1-13) (Seas of Humanity, Trees like people with the fruit of the Holy Spirit.)
“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, 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 possible could wavering and unsettled on the truth. . . .I saw that Satan was at work . . .to distract, deceive, and draw away God’s people, just now in this sealing time. I saw some who were not standing stiffly for present truth. Their knees were trembling, and their feet sliding because they were not firmly planted on the truth. . . .
“Satan was trying his every art to hold them where they were, until the sealing was past, until the covering was drawn over God’s people, and they left without a shelter from the burning wrath of God, in the seven last plagues.
“We are brought out of the darkness of the world into God’s marvelous light. If we received the image of God, if our souls are cleansed from every moral defilement, the seal of God will be placed upon our foreheads, and we shall be prepared for the closing scenes of this earth’s history. But we have no time to lose. The more we study the life of Christ with a heart to learn, the more Christlike we become.
“The sealing time is very short, and will soon be over. Now is the time, while the four angels are holding the four winds, to make our calling and election sure.” SONS AND DAUGHTERS OF GOD, Ellen White (1827-1915) p. 342.
