I personally believe the church continues to build temples to make money. To attend temples, members must pay tithing. All members are told to get a temple recommend which requires tithe-paying. If there is a temple within reasonable distance, the pressure to attend regularly (and pay) is even greater. They claim their temples are based on the ancient Biblical temple but they are not. (See the Mormon Coffee article mentioned below, it's illustrated.)
From Mormon Coffee, posted May 11, 2015:
"...considering the fact that every detail of the biblical temple is clearly presented in the Bible, the Mormon Church knows its assertions are untrue. Which means the Church is willfully deceiving people about Mormon temples."
I've been talking to a friend who is Mormon but has "lost her testimony." She hasn't completely left the church yet and sometimes points out what she thinks are its good points. I remind her on occasion that the LDS church lies to people. They can't claim to have made a mistake, to have erred based on incomplete or wrong information.
How can a church that continues to hide information and lie be a church that serves God?
No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.Matthew 6:24, KJV
