God continues to pour out His wrath on the earth in Revelation 9. Things get worse with every trumpet. And yet we also find the heart of man getting harder and harder in sin. Some will repent, but many shake their fists at God and cling to their idols and sinful ways. This chapter is a call to unbelievers today to repent before judgment falls. And it's also a call to believers to keep a soft heart to God and be on guard from sin's wretched work.
