When Jesus comes again, He will come as a consuming fire. Isaiah asked "Who among us shall dwell with the devouring fire? who among us shall dwell with everlasting burnings?" (Isa 33:14) And then he answers his question and says "he that walketh righteously." (Isa. 33:15) The message of Noah will prepare a people for the coming of Christ, because Noah was "a preacher of righteousness." (2 Pe. 2:5)
