My defense is the witness of the Holy Spirit I have that the revelations Joseph Smith received were true and came from God.
Please explain what that revelation is like for you and how it comes to you. Does it come often or only once?
Just faith is good enough for me!
Why? Why believe in something illogical?
Jesus said:
“A wicked and adulterous generation seeketh after a sign” (Matthew 16:4); and in LDS scripture the Lord has said:
“Faith cometh not by signs, but signs follow those that believe” (D&C 63:9). I believe that is true. That is what I go by.
Okay, but why REJECT things that can be seen? Even Moses had the tablet with the 10 Commandments in hand. God knew the people would not believe Moses if he claimed to have spoken to God but had no proof. God always provides for us to help us in our faith.
The standard scriptures quoted by Mormons relating to the Apostasy and the loss of the priesthood are well known and referenced in many articles and discussions. I am not sure if a useful purpose will be served here by rehashing them again. They would not be acceptable to you, but to us they are.
I think it is very purposeful. Because you claim to have the only true priesthood on the face of the earth, then it goes to show that you (assuming you are male) and all other LDS men believe that they have some sort of power over others. Think future presidential candidates…

I think we should all know why and how Mormons think they have got the corner on the priestly market.
The conviction comes by the witness of the Holy Spirit to us that the Latter-day Restoration is true.
But what about the rest of us? What about people who are offended by the lack of a Christian lifestyle by one certain supposed prophet?
In a way yes. You either believe that he was a prophet of the Lord or you don’t. No amount of argument, miracles, or signs will convince anyone.
No, God would choose someone who was not offensive to so many good people. You are right, arguing away will never convince the majority of people that a person of questionable character would ever be a prophet! That’s because the Bible warned us to be aware of false prophets and we are listening to God.
We don’t believe that it was the miracles that convinced them, but the witness of the Holy Ghost. According to the book of Revelation, in the last days God will allow Satan to perform miracles to deceive the inhabitants of the earth (Rev. 13:14). So performing miracles cannot be a sufficient “proof” to anyone.
Well, then read your Bible. When people were healed or raised from the dead they ran and told everyone they could. Why would Jesus perform miracles if it wasn’t to prove His Divinity?
The whole of the Bible. Jesus talked about the gospel, and that is what Mormonism is.
So when Jesus told Peter “upon you I will build My Church and it will never fall away” He was referring to Mormonism?
Joseph Smith was a bringer of a new dispensation of the gospel, like Moses. That is what he is compared to. Believe it or not, Moses also was a Christian prophet, although he did not live on earth at the same time as the Lord’s earthly ministry.
