John Wesley on Revelation 19:5

And a voice came forth from the throne - Probably from the four living creatures, saying, Praise our God - The occasion and matter of this song of praise follow immediately after, verses 6, Rev 19:6 &c.; God was praised before, for his judgment of the great whore, verses 1 - 4. Rev 19:1 - 4 Now for that which follows it: for that the Lord God, the Almighty, takes the kingdom to himself, and avenges himself on the rest of his enemies. Were all these inhabitants of heaven mistaken? If not, there is real, yea, and terrible anger in God.
