20 But the people who did not die in these plagues still refused to repent of their evil deeds and turn to God. They continued to worship demons and idols made of gold, silver, bronze, stone, and wood-idols that can neither see nor hear nor walk! 21 And they did not repent of their murders or their witchcraft or their sexual immorality or their thefts.
Matthew Henry's Commentary on Revelation 9:20-21
Commentary on Revelation 9:13-21
(Read Revelation 9:13-21)
The sixth angel sounded, and here the power of the Turks seems the subject. Their time is limited. They not only slew in war, but brought a poisonous and ruinous religion. The antichristian generation repented not under these dreadful judgments. From this sixth trumpet learn that God can make one enemy of the church a scourge and a plague to another. The idolatry in the remains of the eastern church and elsewhere, and the sins of professed Christians, render this prophecy and its fulfilment more wonderful. And the attentive reader of Scripture and history, may find his faith and hope strengthened by events, which in other respects fill his heart with anguish and his eyes with tears, while he sees that men who escape these plagues, repent not of their evil works, but go on with idolatries, wickedness, and cruelty, till wrath comes upon them to the utmost.
