21 “The four living creatures…have no rest day and night, saying, Holy, holy, holy, Lord God the Almighty, who was and who is and who is coming”—Rev. 4:8:
3a The emphasis in Revelation 4:8 is that the Triune God is holy and is triply holy, referring to the quality of God’s nature—God’s being; what He is, is holy—Isa. 6:3.
7b Whatever does not correspond to His holy nature, He, as the consuming fire, will consume; thus, He is severe, expressing His holiness in severity—Deut. 9:3.
