D&C 58

There is much "anti-Mormon" that suggest that the Church is not true because some prophesies were not fulfilled.  Of such, the Lord explained -

"Who am I, saith the Lord, that have promised and have not fulfilled?
32 I command and men obey not; I revoke and they receive not the blessing.
33 Then they say in their hearts: This is not the work of the Lord, for his promises are not fulfilled. But wo unto such, for their reward lurketh beneath, and not from above."  (Doctrine and Covenants 58:31–33)

Those authors should beware.
