Money for who? The Morg? No one gets rich in ministry to the LDS and most I know keep their day jobs.
Praying if something is ‘true’ isn’t Biblical at all and “Moroni’s promise” is a straw man. If you don’t get the answer the Book of Mormon is ‘true’ then you either, aren’t sincere, don’t have faith in Christ, or real intent. It comes back to YOU are the one at fault.
And when ye shall receive these things, I would exhort you that ye would ask God, the Eternal Father, in the name of Christ, if these things are not true; and if ye shall ask with a sincere heart, with real intent, having faith in Christ, he will manifest the truth of it unto you, by the power of the Holy Ghost. [Moroni 10:4]
So, where's the angle for more money here mime? I haven't seen a single request for any money, not only on this thread but others.

Unless you want a TR, then it will cost you at least 10% of your income.
