Well, as I read your hypothetical, there are two parts to it: One, a powerful experience has convinced me that god is for real. Two, given that I am convinced that god is for real, should I talk about it with other people?
My answer to the first part is that personal experiences are treacherous. No matter how powerful they were and how sincerely they were felt, they shouldn't convince anyone of anything.
My answer to the second part is that, sure, I would talk about it with other people. My motivation would be twofold: First, true or false, it's an interesting story, and people like to swap interesting stories. Second, if god really existed, that would be an enormously fascinating and important truth about the universe. And being a scientist by training, I find the truth about the universe very important.
That said, I would fully expect my conversation partners to question my standards of evidence and to suggest that my conclusions are honestly mistaken. And they would be right, at least about the first part.

No, not altruism. As I said, my motivation would be to swap interesting stories, which is win-win, not altruism.
