Angels Are Powerful Beings
Angels and demons are very powerful beings.
Paul said that when Christ returns, He will be "revealed from heaven, with the angels of his power: In a flame of fire". (I Thessalonians 1:7-8). The angels who rolled the stone from Jesus' grave after His resurrection (Luke 24:2-4 moved the two-ton rock as if it were a pebble.
The angels can also control nature and the weather. The apostle John wrote in revelation, "After these things, I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that they should not blow upon the earth, nor upon the sea, nor on any tree." (7:1). There are many other references in revelation to the angels' work of intervening in nature to bring about God's purposes or execute His judgement on earth during the tribulation.
Two of the greatest examples of angelic power are n the same book of the Bible. In Daniel 3, we have the story of the Hebrew boys Shadrach, Meshach, and Abednego in Nebuchnezzar's fiery furnace. The king tried to cook them, but an angel showed up in the fire and preserved them (v25). Daniel himself was saved by an angel who shut the lion' mouths when he was in their den (Daniel 6:22)
Demons are also powerful beings. The demon possessed man in Luke 8 was so strong that he could break chains and shackles (v29). Nothing could hold him. According to Revelation 16:13, it will take only "three unclean spirits like frogs" to entice the armies of the entire world to come together in battle against God.
But make no mistake. The power of demons is no match for the power of God. In Pslams 18, there is an creation in power and glory. "[riding] riding upon a cherub" (v10). Verses 7-15 describes this amazing scene, and right in the middle of it is a chrub, one of God's angels.
According to the Scripture the activity of angels as God either sends or withholds them determines what happens in the atmosphere. Thats power!
