Relevant Words of God:
The work of judgment is God’s own work, so it should naturally be done by God Himself; it cannot be done by man in His stead. Because judgment is the conquering of the human race through the truth, it is unquestionable that God still appears as the incarnate image to do this work among men. That is to say, in the last days, Christ shall use the truth to teach men around the earth and make all truths known to them. This is God’s work of judgment.
from “Christ Does the Work of Judgment With the Truth” in The Word Appears in the Flesh
