2 Nephi 33

Nephi laments that he can't write with the same power that he speaks with. He must have been a very powerful speaker! But he points out that whether writing the word of God, or speaking it, what makes the words powerful is the Holy Ghost. For us, being able to understand and know the truth of the scriptures is a matter of the heart. If we read the Lord's words, or hear them spoken, the Holy Ghost is always there to bear witness and it is up to us whether those words will enter and touch our hearts. If we reject the Holy Ghost's testimony, we will reject the words because we harden our hearts. It's never a failure of the Lord's words. Those who reject the Book of Mormon, or any scripture for that matter, do not reject it because it is false, they reject it because they reject the Holy Ghost's testimony. Truth is independent and stands firm and unwavering. Whatever we or anyone else feels about it does not change the fact that it is true.

Nephi's last testimony is very powerful. He has seen the rejection of the gospel, the scriptures and revelation by people in the latter days. In essence he is saying, you cannot accept Christ without accepting his words, and you cannot accept his words without accepting his prophets. The true believer of Christ will accept the words that come from prophets because their words are Christ's words. Otherwise it is like saying I believe in Christ, but I don't believe anything he says. So to reject the prophets and their words is to reject the Savior. Nephi finishes by praying that all will be saved in the last day, but he knows that many will reject the gospel and that will bring about a separation. He also states that everyone that rejects the Book of Mormon will stand face to face with him and the Savior and will be shown with great power that the Lord commanded him to write what he has written.
