Angels. That's who!
Try this out, what one or two angels do:
Genesis 3:24 - a cherubim (really tough angel) with a flaming sword guarded Eden
Genesis 19 - toughed out the Sodom louts.
Exodus 23:20 - guarded Israel
Exodus 33:2 - one angel conquers the promised land
Numbers 22:23 - terrifies Balaam's donkey
Numbers 22: 31 - terrifies Balaam
Judges 6:16 - will defeat Midian
Judges 6:22 - terrifies Gideon
Judges 13:18 - even the angel's name is too powerful to be heard by Manoah
2 Samuel 24:16 - one prepares to destroy Jerusalem
2 Kings 19:35 - 185,000 man army destroyed
1 Chronicles 21:12ff - just one...bent on destroying Jerusalem
You get the picture. No wonder I get worried at Christmas when they say that angels will be in the pageant...scary stuff.
Just remember: we're on the same side.
