As for "shunning" the lavish lifestyle?
That may be that he is not AS extravagant as the others, with bling to spare, lol
BUT I doubt he lives a really HUMBLE lifestyle, such as you or I., (well
me for sure

) I remember specifically one I listened to where he talked about how his wife was dreaming about a house that they happened to walk by, years ago, early in their marriage, how she told him that one day they
would have a big new house like that., and he just shook his head., not quite wanting to believe that., but not directly disagreeing with her.
NOW, he said, indeed they had one
exactly like that., and he attributed that to GOD's goodness in rewarding them for their ministry.
