"Thus saith the Lord of Hosts, Behold evil shall go forth from nation to nation, and a great whirlwind shall be raised up from the the coasts of the earth. And the slain of the Lord shall be at that day from one end of the earth, even unto the other end of the earth: they shall not be lamented, neither gathered, nor buried: they shall be dung upon the ground."
This scene is certainly future; for nothing like it has ever yet occurred since the prophecy of Jeremiah was written; and no such scene will be witnessed till this earth’s final time of trouble shall come. Dan.12:1.
Now if the blowing of the four winds of Rev.7:1 is the same scene (and what would four winds blowing from "the four corners of the earth" produce but "a great whirlwind"?), then the scene of Rev.7:1-8 applies in the last days, and is a work preparatory to the closing up of all earthly scenes. The 144,000 must therefore be found in the last generation of "the servants of our God" on the earth; and the sealing of them must be the last special religious movement among men. It is the closing Christian movement of the Christian age.
The sealing implies protection and salvation. It is a work of the gospel through which all who effectively share in it will secure everlasting life. The threatened condition that is restrained in order that the sealing work may be accomplished is such that when it takes effect, no further work of the gospel can be accomplished; hence, with the sealing of the 144,000, probation ends; the winds of destruction blow from every quarter, and the great whirlwind of God’s indignation, His last testimony in this mortal state against sin, will sweep the world into its final aspect of ruin and desolation."
