Why do presentations like this?

In Australia “religion is meant to be a private thing, isn’t it!”

Yes your decision is yours to make for yourself, but that doesn’t mean it’s a taboo subject. Nor insignificant. To the contrary, we know that taboos only raise the level of ignorance and error.

Sooner or later, everyone asks good religious questions,
and should have access to good expertise.

And if there is a God, we want to know enough about that, to make informed decisions.

Such presentations can clarify life-changing issues, change ways of thinking, behaving, & being. They can even give us the Spirit to keep becoming better people: they in-Spire.

“It is not enough for us, as human beings, just to live. We also must give words to what we are living. Through the word, we appropriate and internalize what we are living.” – Henri Nouwen

The question is not whether to have such presentations, but how to do them well.
