I'm a member of the Church of Jesus Christ of Latter-day Saints
I was born into, but as I grew, I had to know for myself it was true or not. I did a lot of praying and reading, and one day received an answer to my prayers. In this case, the best I can describe is a flow of light and knowledge, and a confirmation to my Spirit that it was true.
From then on I've had more experiences, but that was the start, and that is why I continue on the path I'm on.
