This is just a good thing to be reminded of:

...that the essential thing is "to count conversations more than conversions." If we are always trying to convert people, we'll shortchange conversations -- with all their questions and twists and turns and ups and downs -- and as a result, conversions won't happen. But if we focus on asking good questions and keeping conversations going, conversions naturally occur. At least, that's how it seems to me. Sometimes it's just best to ask questions, like "Tell me about your belief in God," and then just to listen, listen, listen. We may preach more effectively by asking questions and listening than by anything else....
