Genesis 32:22-32 Jacob's Divine encounter.

About Angels
Angels are basically servants of the Lord, also known as Heavenly Beings.
From what is known about them, each Angel has a different task to
perform in Heaven and on Earth.  Since they are invincible, no Evil can
overcome them.  Being invulnerable, they have no concept or experience of
pain or suffering.  They don't ever tire or weaken.  All they know is the joys
of serving & obeying the Lord.  A constant joy that is forever with them.
When it comes all of humanity in the world, they are known to be
supportive.  Sometimes they intervene in ways we can't always see, to
save us from making mistakes, confronting trouble and whenever
in despair.
Much like the classics cartoons, Angels war in our conscious thoughts
against satanic Demons influences, in order for us to make the right decisions.
That's why I've said, "Our thoughts aren't always our own."
Rather than jump, without thinking, into something we'd later regret.
We can not hear Angels when we are out of control, whenever mad.
Having patience is a must when looking to receive guidance from Angels.
This is wise when it comes to important decisions or choices made,
in our daily lives.
Demons are known to dart into our thoughts quickly, so to cause us
to jump to unnecessary conclusions and false assumptions about things
and people.  They are clever in trying to get us to do things that seem
right at first, but end up actually being wrong.  Keeping what's Good & Bad
in frequent check, helps to know when you're being conned by Evil.
Angels can protect us from various harm and help us in our accomplishments.
Angels don't like drawing attention to themself, is why they will at times
blend in as regular human among us.  It is because we're not to
worship in them.
The Bible says that in Thee End Times, Angels will make their presence
known to us.
In revising an old saying to be made right: Where Angels roam, Demons
fear to trend.
Angels In Our Midst

When I once lived in an efficiency apartment, it must of been around
3 AM in the morning.  Something caused me to open my eyes briefly
before falling back to sleep.  As soon as I saw my guardian angel
standing before my apartment entrance door, he started to disappear
fast.  I saw enough to know, that he was tall, wearing a white robe and
his hair slicked back like the famous country singer Porter Wagner.  
There seem to be no particular color variations about his appearance;
just basically a glowing radiant white, all over.  My angel seem to be
looking right at me and smiling.

I was riding my ten speed bike down a main road into town, when suddenly
out of the blue, a car came darting out of a back road, where so many drop
their mail in the mailbox.  Right then I felt an Angel alerted the driver to stop
before hitting me straight on, when they were emerging onto the
same main road.  I was allowed to know that too often in life, persons don't
see how they are saved by Angels, in one way or another, like in the way
that may seem like by luck.  So much we over look in life & easily take for
granted things.  Instead of a lucky chance, I was saved by divine intervention,
right then.
