Angels Holding the Four Winds
This excerpt is from Ellen White with reference to the four winds from Revelation 7.
Four mighty angels are still holding the four winds of the earth. Terrible destruction is forbidden to come in full. The accidents by land and by sea; the loss of life, steadily increasing, by storm, by tempest, by railroad disaster, by conflagration; the terrible floods, the earthquakes, and the winds will be the stirring up of the nations to one deadly combat, while the angels hold the four winds, forbidding the terrible power of Satan to be exercised in its fury until the servants of God are sealed in their foreheads.
Angels are holding the four winds, which are represented as an angry horse seeking to break loose and rush over the face of the whole earth, bearing destruction and death in its path.
A terrible conflict is before us. We are nearing the battle of the great day of God Almighty. That which has been held in control is to be let loose. The angel of mercy is folding her wings, preparing to step down from the throne and leave the world to the control of Satan. The principalities and powers of earth are in bitter revolt against the God of heaven. They are filled with hatred against those who serve Him, and soon, very soon, will be fought the last great battle between good and evil. The earth is to be the battlefield--the scene of the final contest and the final victory.
While their hands were loosening, and the four winds were about to blow, the merciful eye of Jesus gazed on the remnant that were not sealed, and He raised His hands to the Father and pleaded with Him that He had spilled His blood for them. Then another angel was commissioned to fly swiftly to the four angels and bid them hold until the servants of God were sealed with the seal of the living God in their foreheads.
Once the winds are "let loose", destruction will follow.
Prophetically speaking, that's pretty much where we're at now.
