What Is the Remnant?
In John's description of the dragon's battle with the woman and her descendants, he used the expression "the rest of her offspring"
Revelation 12:17 -
And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
That expression means the "remaining ones" or "remnant" (Rev. 12:17). The Bible portrays the remnant as a small group of God's people who, through calamities, wars, and apostasy, remain loyal to God. This faithful remnant were the rootstock God used to propagate His visible church on earth (2 Chron. 30:6; Ezra 9:14, 15; Isa. 10:20-22; Jer. 42:2; Eze. 6:8; 14:22).
God commissioned the remnant to declare His glory and lead His scattered people throughout the world to His "holy mountain Jerusalem," "Mount Zion" (Isa. 37:31, 32; 66:20; cf. Rev. 14:1). Of those thus gathered together Scripture states, "These are the ones who follow the Lamb wherever He goes" (Rev. 14:4).
Revelation 12:17 contains a description of the last remnant in God's chosen line of loyal believers—His loyal witnesses in the last days before Christ's second coming.
