The love that they show is superficial.
As long as you're a JW, they're happy to give you a meal, even give you a place to stay overnight.
But it's CONDITIONAL - are you "in good standing"? Can your elders recommend you? Have you engaged in any immorality or dabbled in "the world" that might contaminate you spiritually?
Now, miss some meetings, be known to frequent bars or date an unbeliever.
That "love" disappears pretty quickly.
