What does the Bible say about the purpose of God's judgment?

In Revelation 8, we see that the trumpets blown represent calamities that serve to warn the wicked of impending judgment. These judgments are not single events but symbolize the ongoing struggles and trials faced throughout history, and they occur simultaneously with God's redemptive work among the elect. Believers may experience pain from such calamities, but these serve to draw them closer to Christ and encourage their faith. In contrast, for the unrepentant, these same judgments serve as warnings, urging them to repent before final judgment comes.
