1. Those with the seal of God (1-12)

The 5th angel blew his trumpet. The fallen star, the Destroyer, opened the Abyss and released destruction on the earth. The destruction was limited in time (5 months) and extent. The locusts would torture godless people until they would long to die. But servants of God who bear his seal would not be harmed. Jesus' people often suffer persecution in a godless world, but on the day of judgment, only those bearing God's seal will be saved.

2. Those who did not repent (13-21)

The sixth angel blew his trumpet and four angels with an army of two hundred million were released and sent to kill a third of mankind. God's purpose in releasing this destruction on mankind was to bring godless people to repentance (20). They did not repent but continued in idolatry, magic arts, immorality, theft, etc. God wants people to repent and be saved, but if people do not repent and accept his grace, there is no way to be saved.

Application: Lord, give me a repentant heart and put your seal on my forehead.
One Word: Repent and be sealed by Jesus' blood
