Love one another as Christ loved us, and when it is genuine, it is active and shows itself in bearing another’s burdens, in forgiving one another, in admonishing one another in love, and in building up each other in faith, this is an evidence of a follower of Jesus. In being hospitable to strangers, some have unwittingly entertained angels, maybe even Christ himself. There are many instances in the Old Testament when this verse was true. I believe that this verse tells us to treat others the same as we would treat Christ. Do I believe in angels? Oh yeah, mine are kept very busy because I must be a handful to protect.
