The interesting thing to me is that there is a video (by WT) about a husband and wife selling their home, moving to an apartment, using their $$ / accomplishments to "further the kingdom".
It is surprising, with all that WT tries to train people to do & think, (Caleb/ Sophia & ice cream $, by god, haha) that it is not working on some.
I dont think there's anything wrong buying things you work hard for, or enjoying it, or even being proud of your accomplishments. No one will argue that.
I think that the point was: surprise... especially for those of us raised in the 60's, to see the change (which is good! Party on!) from the viewpoint "are you really being spiritual buying THAT kind of car?"
Heck, my husband sold his beloved 70 something two door California Mustang to buy a 4 door Datsun (whose vinyl seats cracked in the freezing temps of Maine) to pioneer where the "need was greater"...
And 10 years ago, we have an elder and his fam come rolling into the Kingdom Hall parking lot in this Gigantic Hummer! Getting 1 mile to the gallon, haha!
That's the difference. 😉
