Revelation 9:21 describes people who survive a series of terrifying plagues yet still refuse to turn away from their sins. The verse shows that suffering alone does not produce repentance, because a heart set on its own ways can hear the warning and still stay put. John is recording a vision of God’s judgment on a world that has chosen idolatry and violence, and this line is his summary of their stubbornness.
They didn’t repent of their murders, their sorceries, their sexual immorality, or their thefts.

What Revelation 9:21 Means
The verse begins with “They didn’t repent,” and the key word is repent, which means to turn around, to change direction and mind. The people in view have already seen destruction and death, yet they do not turn. The verse is not describing people who are unaware of God’s power; it describes people who see the consequences and still refuse to change course.
Four sins are then listed: murder, sorcery, sexual immorality, and theft. These cover violence against others, reliance on occult power instead of God, disordered sexuality, and taking what belongs to someone else. Together they describe a society that has abandoned justice and trust, which is why the passage ties this stubbornness to the idolatry mentioned just before it.
The verse does not promise that every suffering person will be saved, nor does it say God has given up on anyone who hears a warning. Its point is narrower: judgment exposes what is already in the heart. Scripture elsewhere shows God calling people to repentance in hope, so this verse is best read as a sober description of hardness, not a formula for who is beyond reach.
The Context of Revelation 9:21
Revelation was written by John, traditionally identified as the apostle, to Christian communities in the Roman province of Asia during a period of pressure and persecution. The book uses symbolic imagery, including locusts, horsemen, and smoke, to reveal God’s justice and the ultimate defeat of evil. Chapter 9 belongs to the sequence of trumpet judgments, which warn the world before the final victory of God.
Verse 20 explains that the survivors continued to worship demons and idols made of gold, silver, bronze, stone, and wood, objects that cannot see or hear. Verse 21 is the direct consequence of that choice: idolatry leads to moral collapse. Reading the verse alongside its neighbors makes clear that the sins listed are not random but flow from a basic misplacement of worship.

Or do you despise the riches of his goodness, forbearance, and patience, not knowing that the goodness of God leads you to repentance?

Paul explains that God’s kindness is meant to lead people to repentance. Read alongside Revelation 9:21, it shows that the same goodness can either soften a heart or be despised, depending on how it is received.
A Short Prayer From Revelation 9:21
Lord, you see the places in my heart where I have resisted your correction and kept my own way. Show me where I have justified sin or ignored the harm it causes others. Give me the humility to turn toward you, to confess what I have done, and to walk in the changes your Spirit asks of me. Let your kindness soften what has grown hard in me, and lead me back to you. Amen.
