Revelation 8:6-7 Now the seven angels who had the seven trumpets prepared to blow them. 7 The first angel blew his trumpet, and there followed hail and fire, mixed with blood, and these were thrown upon the earth. And a third of the earth was burned up, and a third of the trees were burned up, and all green grass was burned up.
All the believers on earth are sealed and protected from these judgments (Revelation 7:3). We know that believers will be in the midst of the judgments God is sending on the unpardoned people on the earth, people who live according to sin and not according to the Word of the Lord, people who refuse to repent of their sins and believe the gospel. How do we know? At the last trumpet the believers who are alive will be changed and those who have died will be raised from the dead and given a new, imperishable body (1 Corinthians 15:50-52). The last trumpet is the seventh trumpet in Revelation. The believers at the time of the last trumpet will be caught up into the clouds to meet the Lord in the air (1 Thessalonians 4:16-17).
The first trumpet judgment brings hail and fire mixed with blood upon the earth. A full third of the earth is burned up along with a third of the trees and all green grass (The grass grows back by the time of fifth trumpet judgment). This is a devastating occurrence upon the earth.
We who are alive at this time need to be warning the people in our sphere of influence to repent of their sins and believe the gospel. We are not to fear. Jesus is telling us ahead of time what is going to take place so we will not fear, but will rather be bold witnesses during that time. Every believer living now is to warn people of the coming judgments and encourage them to take refuge in Jesus by repenting of their sins and believing the gospel (Mark 1:15; 1 Corinthians 15:3-4; Romans 10:9). Are you preparing people for the coming judgments? Are you preparing your family?
