The following information about angels comes from the Hebrew words for angels and numerous verses from the Bible. But, the Bible is the only inspired book on angels, and the only one I used.
Because my latest book requires much study on the topic of angels and demons, I have learned a lot of things about them that I had not previously discovered. Amazing what you can figure out simply by reading and paying attention to the Bible and what it says on a certain subject.
Workers of miracles
Deputies of God
Camp around those who fear God
And then some physical or spiritual attributes:
Have not sinned
Can become visible
Follow God’s order
Can be ranked (chiefs, etc)
Is double the size of Satan’s army
Will oppose Satan
God’s angels are amazing beings that sure can fight, both verbally and physically, and they have many attributes that many people didn’t even know about. For example, did you know angels were priests and prophets? Once again, it is interesting what you can learn with a little study in the Word.
But . . . think about it for a minute. We have a God who loves and cares for us so much that He would create so many guardians, prophets, messengers, priests, etc. to help us. Pretty amazing!
