What Makes it True

This last week I was reading the book of Mark. Christ is talking about how the Pharisees had the truth and they became too absorbed in being in the "true church" rather than focusing on the fact that it was the "true church." Which may not make sense the way I describe it, but basically they became too obsessed with the organization and the rules and lost the importance of the doctrine and love of Christ. I was thinking about this and I believe that I belong to the true church on earth right now. So what makes it true?? It isn't that they people are anymore good or perfect (their are a lot of good people in all churches and their are plenty of jerks that are in my religion) and it isn't the buildings (they are pretty plain actually). The thing that makes it true is the authority and the doctrines. Which are many and I don't have time to to discuss all of them (nor do I completely understand all of them.) However, one thing I was thinking about, in regards to authority, is the sealing power. I know that when I married Rich, we weren't just married for the time that we are on earth, but because we were married by someone with the proper authority from God we are sealed together and will be married even after we die. I feel so blessed to know that.
