Indifferent religion

On the weekend, a friend told me that she's quite happy with there being no God. She asked me what was wrong with that and I said nothing - if she's right. It's only if she's wrong that she's needs to worry. CS Lewis says it this way:

One must keep on pointing out that Christianity is a statement which, if false, is of no importance, and, if true, of infinite importance. The one thing it cannot be is moderately important.

From God in the Dock (Eerdmans, 1994), 101.
