Study the Book of Mormon. Ponder about what it says about God and about God's past doings and mercies toward man. Then go to God and ask him if the Book of Mormon is his revealed word. But do it with the faith that you can and will receive an answer from God and that such an answer will be what dictates your life decisions. Do essentially what Abraham did, take a request claiming to hail from God and test it personally.
Because I frankly can't, and don't expect, to personally convince you against any of your present beliefs or for mine in any meaning full and lasting way, if in anyway at all. We are dealing inherently with an item beyond the limits of human capacity to conceptualize and asertain conclusively or with any real certainty. We can sit back and forth for hours and argue over what and why such is or isn't a right or a wrong reading, or does or doesn't constitute God's will. But I say put it between you and God. God was mercifull and gave answers in the past, why not today? And if someone gives you a reason for "why not" then why trust them or their reading or their claim? It's rather nonsensical to think God would have us base our faith and convictions on merely a human or a human construct when he clearly is omnipotent and, according to many ancient discriptors, certainly used his incomprehensible capacities to give answer to various parts of man kind.

Here's the challenge I've taken, and personally believe any can take and receive answer from God--

Don't take my word for it. I can't force or prove anything really. I hold the issue is between you and God at the foundational level. You make the choices you perceive to be the right ones and I'll leave the reality of such efforts to be a judgement between you and God.
