From atheism to Christianity? How so?

Saying it was a reality you experienced is claiming too much. All you can claim is an internal experience. There is no way to objectively verify it.

You had thoughts and emotions, or possibly a delusion. You cannot dismiss that out of hand.

I don't, but I also recognize that is impossible to completely verify your own rationality, since you are using your own rationality to do that. At some point we all taking a leap of faith in our capacity to reason. My reason was telling me that the evidence was valid, enough at least to continue to pursue that line of reasoning.

Well, you may have once been indifferent to the idea of a god, but you clearly were not a skeptic or a critical thinker.
Your internal experiences do not qualify as evidence.

My rationality is confirmed by the evidence of reality, no faith required.
