How do we treat strangers when they come among us?  We all know (Hebrews 13:2) “Do not neglect to show hospitality to strangers, for thereby some have entertained angels unawares.”  The crisis concerning hospitality that was the concern of 2nd John is a matter of concern also in 3rd John. If 2nd John states the mandate on the negative side, then 3rd John states the mandate on the affirmative side. If we place the two texts together, we have a very wise and encouraging counsel in the matter of hospitality toward strangers
