At religious instruction classes, I encountered The Pilgrims Progress by John Bunyan, and the sincerity of the traveller in that book was overwhelming.
What would I have done if I'd been put to the test? Would I have risked my own life for people I hardly knew? Probably, I would have looked the other way at best or become another apologist for evil at worst.
The real evidence is not practically speaking in scholarship but in how Jesus and the Christianity based on him manifest themselves in the lives of practising Christians. Their lives are the proofs of their beliefs.
