questions that matter

I'm not sure these are the only five questions that matter but I like the list and what I perceive is the intent.

Haddon Robinson says that there are five questions that matter:

1. Is there a God?
2. Has he revealed himself?
3. Did he reveal himself in Jesus?
4. Did the death of Jesus on the cross do anything for anyone else?
5. Did Jesus rise from the dead?

If you start with the last question, he says, it answers all the others.
