Rev 9. In the 5th and 6th trumpet judgments, we see the people of the earth tormented by demons and killed in judgment. Yet the people would rather long for death, than repent of their idolatry and sins. We need to heed the warning of a merciful God.
Rev. 8 The silence of Heaven shows the stillness of the situation as the seventh seal is opened and the trumpets introduced. The first 4 trumpets deal with the creation. In reverent awe, we need to understand the warnings of God as they are given, and repent, trusting in the plans of God.
