There is nothing wrong with being generous, but generosity should be exercised in a wise way, to encourage a change in conduct and circumstance that is to the good rather than the ill.

This is where the Mormon faith can become an issue. Ministry in the name of some generic Christianity can be agreed to among many different denominations, but according to most Mormons, to do Mormonism you have to do it in a Mormon church... and there just aren’t very many, if any, in Latin America. Maybe Beck sincerely thinks that, due to the Mormonism factor, he is doing the right thing.
People from Latin countries makeup about a third of the Mormon religion, and they have many churches.
