Growing up I remember signs along the highway that said, "Radar," or "Radar Enforced" or "Speed Checked By Radar" or some other variation warning speeders to slow down.
Generally speaking, there was no "radar"...just a sign; but the sign was enough to get some speeders to slow down.
Of course, if you don't speed; if you don't break the law, the signs are of no concern.
This scripture, "Be not forgetful to entertain strangers:" is followed by, "For thereby some have entertained angels unawares." Kind of a Spiritual "Radar" sign.
We know radar exists, so a sign warning us of radar can be effective at slowing some people down...it takes more than a sign for some sinners (yes, speeding is a sin)
Do angels exist? The Bible is filled with angelic visitations, so I have to say, "Yes, angels exist." Have I seen one? I don't know...and that's the point.
We are to be mindful of the poor and needy among us...and help, if and when we can; they could be angels God sent to test your resolve. Will you help, or won't you?
When you see a need, is your first thought to fill the need or run away from it?
You see, God doesn't want you to give...he wants you to be giving. It's a matter of the heart, not the head. So don't forget to entertain strangers...they could be angels.
