"And that the voice and work of the third angel blend with that of the first, is plain from his closing words: "Here are they that keep the commandments of God, and the faith of Jesus;" because this is ever the object of the preaching of the everlasting gospel. It is the substance of fearing God and giving glory to him, and or worshiping "him that made heaven, and earth, and the sea, and the fountains of waters."
And the keeping of the commandments of God and the faith of Jesus
is the only thing that will enable any soul to stand in the hour of His judgment, which the first angel declares "is come."
Immediately following the closing words of the third angel is "heard a voice from heaven saying unto me, Write, Blessed are the death which die in the Lord from henceforth"–from this time forward; and immediately following this, are the words: "And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle. And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe. And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped."
And Jesus himself said, "The harvest is the end of the world."
Again: the third angel particularly warns all people against the worship of the beast and his image, whatever these may be; and, from Rev. 19:11-21, we find that the beast and his image are alive when the Lord comes in the clouds of heaven, and are "both" destroyed with the brightness of his coming.
These facts show that the Third Angel's Message is a mighty, threefold, loud-voiced message, which goes forth to every nation and kindred, and tongue and people, just before the coming of the Lord;
---which ripens the harvest of the earth; and which makes a people prepared for the Lord.
And so, it is the last, the closing, message of God to the world.
Such, in a word, in form, in arrangement, is the Third Angel's Message." A.T. Jones
