hmmm. I appreciate you attempting to bring balance to the discussion, but my experience in many many congregations was that not once were we encouraged nor did we think to offer anything but watchtower and awake magazine (or the books we were offering at the time). I was personally discouraged to give a couple of canned goods to the hungry in our community because watchtowers and gods kingdom were the only things that could save them--it was misleading to do otherwise.
Again, I appreciate the balance you're attempting. I'm sure (I'd like to think) there were a smattering of witnesses who took the infirmed shopping or offered some kindness other than to attempt conversion. I certainly never knew any nor was I ever encouraged to do so.
Thanks for your balance and causing me to dig deep in my witness files for information. What I found was vastly different than what's filed in your data banks. Neither are invalid. However, I do believe the official stance of the WTBTS is still that charitable giving is a moot point next to the preaching work.
