I've had extensive contact with LDS (Latter Day Saint, "Mormon") Christians over the last several decades, and I can attest they are in fact much happier and better adjusted (for the most part, there are always exceptions) than JW's. This is due to their positive, life-embracing worldview. In contrast, Witnesses are anti-world and anti-life, simply waiting and hoping for the end of the world so they can REALLY start to live.
In the LDS worldview, unlike Witnesses, marriage and sexual union are eternal. A faithful LDS couple believe they will become a God and Goddess and their deified sexual union will give birth to divine offspring, and they will populate their own world.
All of life in the LDS worldview has been redeemed by Christ and will share in the Resurrection.
Education is strongly stressed, as is family, and comunity. Success in life is strongly encouraged. I've found you cannot ask for better neighbors and co-workers than LDS Christians. Their willingness to help is amazing. My wife and I were helped out of a tight jam by the LDS church in Ann Arbor. We were given nearly three thousand dollars 25 years ago, no strings attached. Try THAT at your local Kingdom Hall or even your local Fundy Church. Or ANY other church for that matter!
If you quote the scripture "give to him that asks" to most LDS Christians, they will obey Christ.
I love Mormon people and the Mormon church. I would BE a Mormon but I know their teachings are simply fantastic delusions. Plus they expect too much time, effort, and money!
The LDS church and people arent fault-free, but if you're looking for a faith community that really seeks to put the Christian ethos into effect, look no further.
