David Alexander grew up Christian but found most faiths to be unfulfilling. After searching for 47 years he found the restored gospel of Jesus Christ and was baptized.

"From then on, I'd listen to conference talks, I'd been studying the Bible and just trying to sort everything out. All these bombs would be going off in my heart -- where everything that I'd learned for 47 years just melted seamlessly into the restoration. It's just the most amazing thing, beyond human understanding as far as I'm concerned. It's like a class triple A miracle! I haven't even scratched the surface of the vastness of the Restoration! As soon as I really humbled myself it just began to open up to me. It still took me another two months after that before faith completely came to me and I heard powerfully and definitively in my heart that the Book of Mormon is the Word of God and that Joseph Smith truly was a prophet of God."
