The Book of Revelation predicts, “And to the angel of the church in Philadelphia write; … Because you have kept the word of my patience, I also will keep you from the hour of temptation, which shall come on all the world, to try them that dwell on the earth. Behold, I come quickly: hold that fast which you have, that no man take your crown. Him that overcomes will I make a pillar in the temple of my God, and he shall go no more out …” (Revelation 3:7, 10-12). The Book of Revelation predicts that a group of overcomers shall be made complete before the disasters. This work of perfecting the overcomers is God’s own work. Is this something that man is capable of doing? How does God perfect this group of overcomers in His work in the last days?
