First of all, I did not say that most Mormons are saved. What I said was, "quite a few of them" are. You might want to get your facts straight before going on another rant. No offense meant.
On to your next point, many people in the Bible, including Moses and Job, "saw God". ("I have heard of thee by the hearing of the ear: but now mine eye seeth thee." - Job 42:5 | "And when Abram was ninety years old and nine, the LORD appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect." - Genesis 17:1) Most of those references refer to the Glory of God, or some physical manifestation of God, so I really don't think you have a valid point there. I'm not here to argue the accuracy of Joseph Smith's testimony; I don't know enough about him to debate it, but I can see where that part could have happened as he recorded it.
He is the image of the invisible God, the firstborn of all creation.
You say that we "will all be held accountable for what we believe", then go on to state that faith is by Grace, not works. If we will be held accountable for anything, then faith is of works, and not Grace. I don't know if that was an error on your part or not, but it is incorrect.
Rom. 3:28-30, "For we maintain that a man is justified by faith apart from works of the Law. 29Or is God the God of Jews only? Is He not the God of Gentiles also? Yes, of Gentiles also, 30since indeed God who will justify the circumcised by faith and the uncircumcised through faith is one."
Rom. 4:5, "But to the one who does not work, but believes in Him who justifies the ungodly, his faith is reckoned as righteousness,"
Rom. 5:1, "therefore having been justified by faith, we have peace with God through our Lord Jesus Christ,"
Rom. 9:30, "What shall we say then? That Gentiles, who did not pursue righteousness, attained righteousness, even the righteousness which is by faith."
Rom. 10:4, "For Christ is the end of the law for righteousness to everyone who believes."
Rom. 11:6, "But if it is by grace, it is no longer on the basis of works, otherwise grace is no longer grace."
Gal. 2:16, "nevertheless knowing that a man is not justified by the works of the Law but through faith in Christ Jesus, even we have believed in Christ Jesus, that we may be justified by faith in Christ, and not by the works of the Law; since by the works of the Law shall no flesh be justified."
Gal. 2:21, I do not nullify the grace of God; for if righteousness comes through the Law, then Christ died needlessly.
Gal.3:5-6, "Does He then, who provides you with the Spirit and works miracles among you, do it by the works of the Law, or by hearing with faith? 6Even so Abraham believed God, and it was reckoned to him as righteousness."
Gal. 3:24, "Therefore the Law has become our tutor to lead us to Christ, that we may be justified by faith."
Eph. 2:8-9, "For by grace you have been saved through faith; and that not of yourselves, it is the gift of God. 9Not by works, lest any man should boast."
Phil. 3:9, "and may be found in Him, not having a righteousness of my own derived from the Law, but that which is through faith in Christ, the righteousness which comes from God on the basis of faith."
It doesn't matter what gospel people preach/believe; if they are of the Household of Christ, they are brethren, to be taught and built up. Also, I understand what you said about not blindly following some doctrine, but earnestly seeking the truth. What I'm saying is that the well established members of the Church should not shun those who are seeking. Maybe you don't understand this, but it is very difficult to break out of something you have been taught your whole life; give them some slack, would you? If someone is diligently seeking the truth, they will find it one way or another.
These might be some hard words and I might appear cruel, however, the truth isn't always nice. The truth hurts! I do say all I say in love because I would be unloving and lying to myself and everyone else if I didn't do what I could to inform someone from the eternal lake of fire. A truly terrifying thought! I pray those of the Mormon faith that I encounter maybe changed by the pure Gospel of our Lord and Savior, Jesus Christ.
