“Then I saw another mighty angel coming down from Heaven. He was robed in a cloud, with
a rainbow above his head; his face was like the sun, and his legs were like fiery pillars.”
This mighty angel is Christ. Being clothed with a cloud is different than being on a cloud. He is not yet in the open; He’s in secret descending from Heaven from Heaven. Revelation 1:7 and Matthew 24:30 let us know that He’ll come out of secret when all tribes see Him. The rainbow around His head signifies that He will keep the covenant God made with mankind after the Great Flood. It also shows that He will execute judgment according to God’s judgment. Legs like fiery pillars indicate He will be steadfast and in God’s glory. The little scroll in His hand is the scroll in 5:1. In 5:1 it was still sealed but here the seven seals have been completely removed. It is only part of the scroll and we know this because here it is referred to as a little scroll. The main part of the scroll has been revealed.
In saying that “He planted his right foot on the sea and his left foot on the land…” it indicates that He is taking possession of the earth back from Satan. When verse 3 says He roared like a lion, it is letting us know that Christ wrath. A roar of a lion is likened to a king’s wrath in Proverbs 19:12 and 20:2. The seven thunders show the full and powerful wrath of God. In verses 6-7 Christ is saying that with the seventh trumpet comes the most serious of His wrath, the final answer to the martyred saints’ prayer we sawing in Revelation 6:10. There will be no more mystery in God. In Isaiah 2:2-4, 11:1-10, 65:17-20, and 66:22 God made promises of the kingdom in its manifestation coming, and the new heaven, the new earth, and the new Jerusalem. They will be revealed to all.
