I go to church sometimes because my mom likes it when I go, but I'm not particularly religious and even if I was, I don't believe you need to go to a church to be close to God.
I've been to many churches and sects ... Most of them preach intangible wealth. EG: Follow their teachings, and you'll be rewarded in the afterlife or be blessed in some immaterial way.
From personal experience, the ONLY ones preaching *literal* wealth were the ones asking for more and more money.
