Revelation 9:20-21
But the people who did not die in these plagues still refused to turn from their evil deeds; ... and they did not repent of their murders or their magic arts (witchcraft) or their sexual immorality or their thefts.
These things are what will be prevalent in the World during the Great Tribulation, and are even now regularly practiced among those who live today. It is amazing that, even though God patiently waits, and, in turn, sends blessings and tragedies, still there are those who refuse to humble themselves before God and admit that He alone deserves their worship and homage. No matter what God does to them, whether good or bad, all without a doubt and obviously His doing, they still remain stubbornly brazen with their rebellion and hatred for everything that is decent and honorable.
God has proved Himself perfectly just when He condemns the wicked. And perfectly good and gentle and loving in His grace and mercy to us who have recognized His sovereignty. Even though it is of God and not we ourselves that we have turned to Him; it is all God. He sets up and throws down. He punishes and forgives. And He alone deserves all the credit for it all, all the honor and glory.
Even so, come, Lord Jesus!
