Certainly the Church of Jesus Christ of Latter-day Saints has shown good fruits (results for many people, across generations), that I have seen personally.

• We believe anyone can know for themselves if the Church of Jesus Christ of Latter-day Saints is God's official organization on the earth.
• Having observed and read much, it is simply the best, where "much" and "best" are...
• The Church's "About us" page (a decent overview)
• MANY RESOURCES: search by topics, at www.churchofjesuschrist.org (magnifying glass icon): includes a very good 12-step program, & much, much more. (main)
