Sooner or later it comes down to faith

In one of my classes, after discussing a number of difficulties and
issues related to the creation stories in Genesis, a student chimed in
that sooner or later one simply has to have faith.

I didn’t disagree, but instead asked: What sort of faith, and faith in what?

We had already read part of Paul Tillich’s classic The Dynamics of Faith, and so students were aware of the possibility of other ways of thinking about faith.
