Angels

God made two very separate creations:
Heaven creatures
Mortal creatures

In the Heaven:
Angels
Seraphim
Cherubim

On Earth:
The animal kingdom
Man

Since the Bible deals with man's relationship with God and/or visa-versa, we are a bit light on anything outside of that relationship.

Angels are intriguing, they seem like us, but in reality are far greater than we ... or are thy?
Some worship angels, almost as if by superstition.
Some denounce that angels even exist.
Others believe they are here for your beckoned call.

So, anytime there is a dichotomy of belief - you have to go back and recenter on the Bible.

Matthew 18:10  - Angels are real, exist in Heaven
Matthew 26:53 - Jesus says they are real
Colossians 1:16 - They are created
Job 38:6-7 - They were before the Earth existed
Jude 6 - Some have/had free will
1 Peter 1:12 - They do not know everything nor understand
Luke 2:13 - There are many angles
Hebrews 1:13-14 - They served the Called
1 Timothy 5:21 - There are angels
Psalms 8:4-8 - Man is created lower than the angels
2 Peter 2:11 - Angels are not judge
Hebrews 12:22 - Angels are without number

Obviously, angels are not there to be worships, nor to serve us, but they do exist!

Some have seen angels and it generally scares the tar out of them.
Some have been helped by angels, they knew not why.
Some have never seen angels though have been struck at how odd situations resolve.
Some have heard angels speak, always with something they need to know in warning.

Some pray to see an angel and I do not think they know what they are asking.
To be confronted by an angel, timeless beings whom stand before the most holy, we are judged by sin and worthy of the death only Jesus blood can cover, no ... they are not happy with mankind but are held back by God.  In fact they find God's interest in us a mystery.

And let us not forget that there is the dark side of angels, those whom fell with Lucifer, barred from Heaven, under judgment ... but perhaps another time ....
