somethings that make us different

I was talking to my roommate the other day and he was talking about how every church is basically the same. Except for maybe a few small things, but that they are the same. It didn't feel or sound right so I've been thinking about, what makes us different. What makes us the one true church. That part my roommate and I get into about sometimes because he is Catholic and I'm obviously LDS. He likes to say that the Catholic church is the one true church because its been around for a long time. I would come back with that I know that ours is the true church. He'd ask me how and my only answer is that I just know. Just because a church is old, doesn't make it the true church. Then I realized, how can I properly explain that its true. I can easily go on faith alone.. but not everyone does. During the testimony meeting, a sister stated that it is/can be hard for one with an analytical mind to have faith.

The following scripture has been floating in my mind:

"Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed" John 20:29

I understand that and although I don't need proof its true, I was still thinking about how can I explain it to someone else that does need proof. Then the following answers came to me:

1. The Book of Mormon which is another testament of Jesus Christ. All you need to do is read it or at least read part of it and you will know of its truth. I seriously doubt there is anyone out there that can honestly say they have read the Book of Mormon and still say they don't believe. It corroborates with the Bible with events that happened and prophecies that came true. We are the only ones that have another book testifying to us. Every other Christian church goes off just the Bible. 
2. The Prophet Joseph Smith. He is a man that was born in New York that when he was a teenager went into the grove - now the sacred grove - and prayed. He was visited by our Heavenly Father and Jesus Christ in person. He reestablished the church upon the earth.
3. Our Latter-Day Prophets. We are the only ones with modern day prophets. They help guide us and let us know what we need to do. 
4. The Apostles. We are the only ones that have 12 apostles as Christ did in his ministry.
5. The Priesthood. We are the only ones that have men who have priesthood authority. 
6. The Word of Wisdom. Other churches have something similar, but we have actual doctrine. The things in the word of wisdom are stated in the Bible as well. 
7. Its a lifestyle. We're one of the only ones where you actually live the gospel. Not where the rules only apply on Sundays. Or when its convienient. 

Something that comes to mind is something a friend of mine said. There is more anti-Mormon literature than any other religion. So you wonder why is there so much against Mormons? The church has got to be true..

Its not an exact quote, but its pretty close. I just think its interesting.
