Yesterday, angels were sent out with plagues and bowls were prepared for pouring. Today, we get to see the dramatic moments when the bowls are poured. Each plague is horrific, especially when we recognize the wholeworld is experiencing each plague. Everyone, from everywhere, will be affected by these plagues.
(As a quick aside, that means all people who have chosen to turn their backs on God. Remember these plagues and bowls are the wrath of God upon those who chose to reject Him [see Rev. 15]. God has promised that we will not taste his wrath but his salvation, as we chose to follow him. [1 Thess. 5:9])
First, Sores cover those who worship the beast. Then, the sea becomes blood and all life dies. Rivers and streams turn to blood, so blood is the water over the whole earth. Then the sun begins to burn people, followed by the Kingdom of the Beast being plunged into darkness. Penultimately, Euphrates is dried up.
The reason we will stop at six is because I think the important part for John, what SHOULD shock his readers then and now, are the parts where he talks about the reaction to the plagues, what the people chose to do because of the plagues.
In verse 9, we see the sad and shocking reaction of those who are being effected by the plagues. Even as they have experienced the plagues and they know the plagues are coming from God, they choose to blaspheme His name and do not repent or give Him glory. Those who suffer the plagues are continuously, with full knowledge, rejecting the God of heaven after the plagues and bowls. They are not accidentally rejecting Him, or acting in ignorance. They are choosing to reject the God they KNOW is sending these plagues. They reject Him after the fourth bowl (9), and the fifth bowl (11). After the sixth bowl, demons round up the people of the world in their final rejection of God. The seventh bowl, poured out at the Mountain of Megiddo (Har Megiddo or Armageddon), is upon all those who have blasphemed God and continued to blaspheme Him.
Earlier I said it is sad and shocking that this is the reaction of those who choose not to follow God. But the truth we must see is that God is giving everyone a choice. He shows us that even with clear evidence that YHWH is the God of heaven and Earth, some will still refuse to repent and follow Him. The question for the original recipients of Revelation, and for you and I, is this : are we among those who refuse to repent and acknowledge God, or do we give Him the glory he deserves, and choose to do his will?
The choice is yours.
