The Lord placed the church under condemnation because they treated lightly the Book of Mormon, even in its imperfect state, it being the most correct book according to Joseph, the writers in the Book of Mormon stated that these things are precious for our souls and wrote them for our day to be a benefit to us. God validated the truthfulness of the Book of Mormon, then we ought to use truth to establish what is error. The scriptures should be our standard for establishing truth, not our only exclusive standard but a standard nonetheless.
It's not an either or, Joseph or Denver pitted against the scriptures, either the scriptures are right or Joseph and Denver are right in essence is what is being said, and one or the other must be false and neither can be true, I fail to see where either one of them did or taught things contrary to the scriptires. To come to that conclusion one would have to believe that both Denver and or Joseph consistently taught and have said things contrary and contradictory to the scriptures to contrast it in that light or that the scriptures are utterly false. I have found the scriptures to be truthful, they have always been a guide to me, a standard for truth and if I lacked wisdom or understanding I turned to the scriptures and then asked of God and He has unfolded the scriptures and shown me the plainness and truthfulness of them. I have also found Josephs words to be of worth and I have found Denvers words to also be of worth and have been blessed and enlarged in my life by them.
For the soul who is wondering around lost, who cannot get answers to prayers, who the spirit doesn't manifest itself to them, do they believe the words contained in the book and what it says about itself or do they just not believe and if they do not believe then how can one come to know the answer, if they ask, and pray, it's because they exercised faith as the book says to do, so they must believe so as to be able to get an answer even if that belief is small. As Nephi taught, If they don't believe at least believe Christ, and if you believe Christ then you will also believe these words, and He will manifest it to you by the power of His spirit. If He has not manifested it, one ought to examine why, are the words untrue or is it because one does not believe and they ask in vain, knowing already in their heart what they will or will not believe. In other words, if one inquires of Him and is not sincere, they essentially are tempting God by not coming to Him in humility but instead came seeking signs and for Him to disprove their own unbelief before they would believe. Even then they still would not believe. So what does it profit them to have a witness then to be brought under further condemnation by it.
If you be the son of God turn this stone into a loaf of bread, or cast your self down and the Angels will preserve you, so you do not dash your feet against the stones. We ought to believe in Christ and ask in all sincerity with humility.
And I said unto him: Lord, the Gentiles will mock at these things, because of our weakness in writing; for Lord thou hast made us mighty in word by faith, but thou hast not made us mighty in writing; for thou hast made all this people that they could speak much, because of the Holy Ghost which thou hast given them;
24 And thou hast made us that we could write but little, because of the awkwardness of our hands. Behold, thou hast not made us mighty in writing like unto the brother of Jared, for thou madest him that the things which he wrote were mighty even as thou art, unto the overpowering of man to read them.
25 Thou hast also made our words powerful and great, even that we cannot write them; wherefore, when we write we behold our weakness, and stumble because of the placing of our words; and I fear lest the Gentiles shall mock at our words.
26 And when I had said this, the Lord spake unto me, saying: Fools mock, but they shall mourn; and my grace is sufficient for the meek, that they shall take no advantage of your weakness; (Ether 12)
