For a Christian, Jesus is the unique and only way that God has fully revealed himself. For a Jew this cannot be.

I was not comfortable worshipping another Jew.

I still go to a Christian priory for retreats.

Only God Himself fully appreciates the influence of a Christian mother in the molding of character in her children.

I thought of such Christian inventions as the ghetto and the Jewish badge of shame. The Nazis didn't have to go very far to pick up their know-how.

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.
