I have several problems with your post, but ill start off with just one.
Can i ask you, if a Mormon comes up and tells you that if you read the Book of mormon with a sincere heart and an open mind and a willingness to believe, that he will gauruntee that you will convert to mormonism, and after reading the book of mormon with what you believed was a sincere heart, open mind, and a willingness to believe, you didnt convert or werent convinced, what would your thoughts be on both the challenge/argument, and your position on Mormonism?
You may attempt to make a problem out of my post, but I assure you there's nothing wrong with it. I've met quite a few Mormon's, actually. A old friend of mine had a Dad who was a deacon in the Mormon church. However, the things Joseph Smith claims are not consistent with the message we get from the Bible. And since he claims to have been inspired by it, that just doesn't make sense. Did you know that the elders of the Mormon church appoint a new "prophet" every year? It's kinda like how the Roman Catholic church picks a pope. But, men consenting their vote to establish such a thing will never be the truth.
The difference between what I suggested to you and what you're attempting as a comparison is that the contents of the Holy Bible are actually true. It won't work the same way if you try to believe something else. But, no one is forcing you to believe. I told you how you can find the truth, but evidently you don't really want to know and aren't willing to try. It's no skin off my back. It's really not my problem. But if you're not willing to believe the truth then you can never find out.
God already knows He is faithful, so it's really not something He has to prove. But if it's something you want to understand experientially then you have to enter into the terms God has established and provided for us knowing it. If that's not what you want then believe which ever lie you choose. Like I said, it doesn't bother me any. I'm still going to know the truth that God told me and which will never change. Have you considered that maybe God has not called you or chosen you? Maybe He doesn't see you fit for service toward Him? Maybe in His providence He never meant for you to enter heaven and has consigned to you a void and vain life of wasteful searching which will never produce the glory of His truth?
