Is that not a rather bold claim to say you are the restored church of Jesus Christ, where does that place the rest of believers, do you think we are lost or deceived
The claim of our Church is very bold, in my opinion. It is not intended to be offensive, however. The reason our church spends so much time, effort, and money on missionary work is because we really do believe it's true and really do believe it's an important message for all of humanity, including those who are already Christian. Our message is a message of love for everyone. Why else would we spend so much effort on spreading the message to the world? If anyone thinks that our top church leaders get some special personal gain or financial bonus based on conversion rates, they are very, very, very mistaken. President Hinckley did not choose to run our Church. He was called of God and now spends nearly every waking moment working himself to the bone to spread the message of truth. The motivation is pure. Even if you don't accept the message as true, I absolutely and positively guarantee, that if you spent the time to get to know the Prophets and Apostles today, to understand them and their lives, you would agree.
Where does it place the rest of believers? I believe I have someting as a church member that other beievers do not have. They need it. God wants them to have it. The fact that I believe this, does not mean that I think I'm better than someone who does not yet have what I have.
Do I think you are lost or deceived? Lost? I'm not sure what that means. You have not yet found the fulness of the truth of Christ. The Lord Jesus Christ may be more pleased with the way you live your life, than he is with the way I live my life, but he still wants me to offer you the truth that I have. It will bless your life. You need to receive the saving ordinances, as only performed in The Church of Jesus Christ of Latter-day Saints. The sooner you do, the better off you will be. These ordinances are even offered to those who have died and are in the Spirit World. Do you have any idea how much time and energy our church spends researching genealogy and performing vicarious ordinances for the dead in our temples? Why in the world would we do this if our motivation was anything other than pure? What possible gain is there?
Are you deceived? To some extent, yes. You understand an awful lot of truth, but to whatever extent you believe in false doctrines or false biblical interpretations which developed over the centuries, to that extent you are deceived.
Does that mean that I think I know more than you? Sometimes, yes, and sometimes, no. You may have a better understanding of parts of the Bible than I do and you may have better insights than I do into some profound scriptural meanings. I assume I could learn a lot from you and other Christians in this regard. However, I believe there are some important things that I understand that you do not. This would be things concerning the nature of the Godhead, the plan of salvation, the necessity of priesthood and other things only taught in my church.
Do any LDS ever get arrogant because of the things we believe? Probably. Is that a sin? Yes. Is it justified? No.
Are we better than other people simply because we belong to the true restored Church of Jesus Christ? Absolutely not.
