Jesus Army evangelism

I can tell another person what I’ve experienced, but I can’t transfer that feeling to them as if I was exposing them to the flu. As Allen says “our experience may play an important role when sharing Christ with non-believers, but it may not provide the cogent force necessary to overcome intellectual barriers to faith.”

Let’s put it this way: If I’m talking to a Buddhist who claims to have experienced Nirvana and I am only able to respond by describing my own experience of encountering Jesus, what differentiates my experience from his? Do I have any evidence that what I encountered was the one true God while his experience was just some kind of meditative high?
