You would think the name of the church would clue most people in; The Church of Jesus Christ of Latter-day Saints, but there are many out there that claim other wise for various reasons.
One of my favorite scriptures 2 Nephi Chapter 25:23-26
23 For we labor diligently to write, to persuade our children, and also our brethren, to believe in Christ, and to be reconciled to God; for we know that it is by grace that we are saved, after all we can do.
24 And, notwithstanding we believe in Christ, we keep the law of Moses, and look forward with steadfastness unto Christ, until the law shall be fulfilled.
25 For, for this end was the law given; wherefore the law hath become dead unto us, and we are made alive in Christ because of our faith; yet we keep the law because of the commandments.
26 And we talk of Christ, we rejoice in Christ, we preach of Christ, we prophesy of Christ, and we write according to our prophecies, that our children may know to what source they may look for a remission of their sins.
This was written by a Prophet of God, Nephi who was preaching to his people hundreds of years before Jesus Christ was born in to the world. It is from the Book of Mormon a second witness of Jesus Christ, a companion to the Bible. Where the Bible mainly deals with the Jews, the book of Mormon deals with people who were led to the American continent, during various exoduses from Israel by the tribes. (John 10: 16 And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be cone fold, and one shepherd) Mainly it deals with a Prophet named Lehi and his children who lived around the time of Jeremiah during the first year of the reign of King Zedekiah and were told to leave Jerusalem after testifying of the prophecies that Lehi had received from God and of the wickedness of the Jews and their abominations 1 Nephi 1:20 And when the Jews heard these things they were angry with him; yea, even as with the prophets of old, whom they had cast out, and stoned, and slain; and they also sought his life, that they might take it away…
The Book of Mormon has many passages about Christ, his church, teachings and prophecies.. Alma 46:15 And those who did belong to the church were faithful; yea, all those who were true believers in Christ took upon them, gladly, the name of Christ, or Christians as they were called, because of their belief in Christ who should come.
