All of those are fairly good reminders, except the very last one. Reasonable people don't join the church only because of emotional experiences, positive examples and companionship. They have to be rationallly convinced as well. Debating is simply the best way to do that, provided you know your facts well enough to answer the questions instead of just saying, "Oh, it's a mystery" or something to that effect. Debating is simply the surest way to do that. Dialogue tends to be more grabbing than monologue. It is a far surer way of convincing someone than handing them a book they may never read a word of and that can't speak and so can't answer all their personal doubts.
