When I was still going to meetings, there was an experience of person becoming a new study.. The pioneer sister said she had called (phone service) this person for several years and never got a response. One day, the person answered the phone and was all in a panic- instead of going with her presentation the pioneer asked if she could help in any way. She ended up taking the lady to work, picking her up in the evening- and helping somehow with the lady's adult daughter. Now the pioneer drives her to all the meetings, and they are studying.
I remember quite a few years ago at a DC a pioneer said she can do D2D service in deeds, like carrying someones groceries, asking them if they need help or what not... I wonder if she slipped a tract in the boxed goods bag, or used one of those lines 'the reason I was so helpful today, was because I am a JW...'
If I was never involved in religion, I don't know how I would react to a stranger telling me they have the truth at my door.
