This message was preached at New Testament Christian Fellowship in Conover, NC on January 21, 2018. The primary focus is the stern reminder given in verse 15, a reminder for us even now: WATCH & KEEP OR ELSE! The following biblical truths are also exposited: devils most certainly work miracles (16:14), the gathering of Revelation 16:15 is also pictured in Psalm 2; and though the devils gather, it is ultimately HE who gathers for HIS purposes (16:16b). A brief introduction is also provided concerning the place of Armageddon.
