Let me introduce you to sister Nikki Yaste -- she has tattoos, listens to Nirvana, used to work as a stripper and a porno model -- and is now a devoted mother to her son, adores Relief Society, and watches LDS General Conference with all the wide eyed wonder of a kid as Christmas.
Her conversion has been miraculous, as well as heartbreaking.
If you want to follow the story of a living example of the hymn "I Stand All Amazed," I urge you to read her blog
LDS Woman At The Well. You will not get through it without a dry eye, I guarantee.
After the kind of life she used to lead (and endure) she now charges through her world with a testimony that has all the fire of Paul and Alma the Younger. It is wonderful to follow.
