In the visions John received, on the island of Patmos, in the first century, there is a lot of talk about angels.
Christ sent His angel to John to make known His revelation (Rev 1:1). Thousands and thousands of angels encircle the throne in Heaven (Rev 5:11; 8:2). John saw 4 angels standing at the 4 corners of the earth (Rev 7:1). In Rev angels seem to have a lot of authority under God (Rev 8:2, 6). There is hierarchy amongst the angels (Rev 7:2-3; 10:1; 14:18). Angels are messengers sent by God to His people (Rev 22:6). Some have royal, priestly functions in Heaven (Rev 15:6). There are also mighty angels of warfare (Rev 12:7). Angels proclaim the gospel to people (Rev 14:6). Angels warn humanity (Rev 14:9). Angels are vehicles of God’s judgment (Rev 16:1; 20:1-2). An angel carried John away in the Spirit into the desert to reveal future things to him (Rev 17:3). An angel carried John away in the Spirit and showed him the New Jerusalem (Rev 21:10), and the river of the water of life (Rev 22:1). An angel explained “mysteries of God” to John (Rev 17:7-18). The earth can be illuminated by the splendour of an angel (Rev 18:1). Angels prophesy (Rev 18:2-3, 21-24; 19:9; Rev 22:6). Angels view themselves as fellow servants of God along with the Christian church (Rev 19:10; 22:8).
So, before we write off angels as being somewhat insignificant compared to say, the Spirit, let’s take a fresh look at their glorious significance in the Kingdom of God.
