At that time Merodach-baladan the son of Baladan, king of Babylon, sent envoys with letters and a present to Hezekiah, for he heard that he had been sick and had recovered. And Hezekiah welcomed them gladly. And he showed them his treasure house, the silver, the gold, the spices, the precious oil, his whole armory, all that was found in his storehouses. There was nothing in his house or in all his realm that Hezekiah did not show them. Then Isaiah the prophet came to King Hezekiah, and said to him, “What did these men say? And from where did they come to you?” Hezekiah said, “They have come to me from a far country, from Babylon.” He said, “What have they seen in your house?” Hezekiah answered, “They have seen all that is in my house. There is nothing in my storehouses that I did not show them.”
Then Isaiah said to Hezekiah, “Hear the word of the LORD of hosts: Behold, the days are coming, when all that is in your house, and that which your fathers have stored up till this day, shall be carried to Babylon. Nothing shall be left, says the LORD. And some of your own sons, who will come from you, whom you will father, shall be taken away, and they shall be eunuchs in the palace of the king of Babylon.” Then Hezekiah said to Isaiah, “The word of the LORD that you have spoken is good.” For he thought, “There will be peace and security in my days.”
(Isaiah 39 ESV)
And the fifth angel blew his trumpet, and I saw a star fallen from heaven to earth, and he was given the key to the shaft of the bottomless pit. He opened the shaft of the bottomless pit, and from the shaft rose smoke like the smoke of a great furnace, and the sun and the air were darkened with the smoke from the shaft. Then from the smoke came locusts on the earth, and they were given power like the power of scorpions of the earth. They were told not to harm the grass of the earth or any green plant or any tree, but only those people who do not have the seal of God on their foreheads. They were allowed to torment them for five months, but not to kill them, and their torment was like the torment of a scorpion when it stings someone. And in those days people will seek death and will not find it. They will long to die, but death will flee from them.
In appearance the locusts were like horses prepared for battle: on their heads were what looked like crowns of gold; their faces were like human faces, their hair like women's hair, and their teeth like lions' teeth; they had breastplates like breastplates of iron, and the noise of their wings was like the noise of many chariots with horses rushing into battle. They have tails and stings like scorpions, and their power to hurt people for five months is in their tails. They have as king over them the angel of the bottomless pit. His name in Hebrew is Abaddon, and in Greek he is called Apollyon.
The first woe has passed; behold, two woes are still to come.
Then the sixth angel blew his trumpet, and I heard a voice from the four horns of the golden altar before God, saying to the sixth angel who had the trumpet, “Release the four angels who are bound at the great river Euphrates.” So the four angels, who had been prepared for the hour, the day, the month, and the year, were released to kill a third of mankind. The number of mounted troops was twice ten thousand times ten thousand; I heard their number. And this is how I saw the horses in my vision and those who rode them: they wore breastplates the color of fire and of sapphire and of sulfur, and the heads of the horses were like lions' heads, and fire and smoke and sulfur came out of their mouths. By these three plagues a third of mankind was killed, by the fire and smoke and sulfur coming out of their mouths. For the power of the horses is in their mouths and in their tails, for their tails are like serpents with heads, and by means of them they wound.
The rest of mankind, who were not killed by these plagues, did not repent of the works of their hands nor give up worshiping demons and idols of gold and silver and bronze and stone and wood, which cannot see or hear or walk, nor did they repent of their murders or their sorceries or their sexual immorality or their thefts.
(Revelation 9 ESV)
Revelation 9: In His sovereignty, God uses Satan and his forces of darkness to inflict His judgement upon the earth. The fallen “star” (or angel) is given the role of carrying out punishment upon sinful humanity, but he is only given such authority by Christ Himself who holds the keys of death and the bottomless pit. How might this alter our typical view of spiritual warfare being a cosmic battle of two equal powers (God and Satan).
The fact that God gives Satan and his forces the role of carrying out His judgment ought to serve as a startling reminder that sin is much more serious than we tend to think. However, this ought to also encourage us as God’s people knowing that neither Satan nor his evil forces possesses the power to unleash hell on earth unless they are first given the power by our Lord Himself to do so. Therefore, those who are sealed can rest secure in the supreme authority of our Lord knowing that nothing can separate us from His sovereign protection. We are more than conquerors through Christ who loves us. Neither death nor life, nor fallen angels nor demonic rulers, nor things present nor things to come, nor powers, nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.
