Pre Earth Life: "
5 Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations."
First of all why would GOD show this to one person instead of a multitude? The accounts of Jesus Christ are written by multiple witnesses. Any error would be corrected by those who witnessed Jesus' resurrection.
First, you're reasoning about why God would not reveal himself to only one person eliminates quite a few prophets, including Moses. And second, God has spoken to me, personally, through the spirit, testifying of the truth of JOSEPH Smith's revelations and teachings, as well as to the truth of the Book of Mormon and the status of the modern day prophets of our church. The same is true of many millions of Mormons, so he HAS revealed the truth to multitudes. If you'll take the time to research the history of the Church of Jesus Christ of Latter Day Saints, you'll also discover that Angels and Christ himself appeared to more people than Joseph Smith during the early years of the church.
So how does a single person born about 2000 years afterward have the right to change GOD's word? Since GOD is all knowing why would he change it?
This statement seems to imply that you don't know about the council of
Nicaea 1 and
2, both of which changed what is considered "the word of God" today. Beyond that it also implies that you are unaware that the New Testament itself was not assembled into a coherent book until hundreds of years after the events described. And then, of course, we have this:
Paul on the road to Damascus
Acts 9:7 "And the men which journeyed with him stood speechless, hearing a voice, but seeing no man."
Acts 22:9 "And they that were with me saw indeed the light, and were afraid; but they heard not the voice of him that spake to me."
Life is not about good works. It is only through trust in Jesus that we are saved.
James 2:
"17 Even so faith, if it hath not works, is dead, being alone.
18 Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works.
19 Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
20 But wilt thou know, O vain man, that faith without works is dead? "
And then there's the following combination:
John 17:3
"3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent. "
1 John 2:4
"4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him. "
All this comes down to one concept. Blind faith in any creed or doctrine is not what God wants from us. What he wants is for us to come to him as best we can. Pray to him, seek truth, and obey the promptings of his spirit and you'll be fine in the next life. If the promptings of God's spirit really direct you to attack other Christians over points of doctrine, more power to you, have at.
