In the long run, it may be best for them to post here in the midst of other religious topics. That way their error is seen *and* addressed by the rest of us, so that Bible novices won't get sucked in.
It is very difficult to convert a Mormon because they are so bought into the idea that the Bible has been corrupted, and that we need "Another Testament". We must show them that the Bible is what it says it is: true, inspired, complete, and perfect.
Some golden facts about Mormonism -
1. They will claim (at first) that they support and believe in the Bible...as long as it suits them. Once you show it where it convicts Mormonism for the fraud that it is they will turn on it like a pit bull.
2. *Any* religion that seeks to advance its own purposes by attacking the Bible as contradictory, incomplete, and corrupted is NOT a legitimate religion.
3. The Bible is the perfect, imperishabble and enduring word of God that contains all things that pertain to life and godliness, that the man of God may be complete, equipped unto every good work. This rules out the need for the BOM. John 20:30-31, 2 Tim 3:16-17, I Peter 1:23.
4. Most of the time Mormons will agree that if we pick up the Bible, read it, believe, and obey what it teaches then we can be saved. This also shows we do not need the BOM.
5. Gal 1:8 specifically warns against anyone - even an angel - bringing another Gospel (and the BOM identifies itself as "another Testament"...same concept).
And no ibmagg, I won't be responding to this particular thread again. Enough of my limited time is already eaten addressing the other two threads we have been on. Unlike you, I am not retired (and congratulations on that, BTW).
Acts 2:38...this means you!
