"Be not forgetful to entertain strangers: for thereby some have entertained angels unawares." Hebrews 13:2
Truths like this have almost been conditioned out of us. If you are wondering what entertain means in the Greek, well it means to be hospitable; to show them around and give them a good time. I'll bet you can count on one hand who you can talk to about verses like this. It's just not accepted that angels live among us and can at times materialize so we can see them. (It's a lot easier to just think of angels as figures mentioned in the Bible. Some of the Bible characters had an experience with an angel but none of this was meant for our day.)
It's scary. We should be listening to God and working with the angels to accomplish our goals in life. But our religious experience might be better described like this:
Watered down preaching so as not offend newcomers
Or fire and brimstone preaching where all of the liberties given to us by Jesus are called sin
Along with Bible illiterate Sunday School teachers taking their turn because they have to
Mixed with careless actions on behalf of those who claim to be following Christ
The faithless teaching the hungry how to be faithless
The powerless teaching new believers how to be powerless
No wonder we don't believe in angels unawares.
The Bible has become static to many who are looking for some sign or some extra biblical move of God. But the Bible is not static truth, with some stories fitted in for our entertainment. The Bible is alive and within it are volumes of truths and millenniums of prophesy and today's voice of the Almighty, clearly and succinctly spoken to anyone who will lend an ear.
