I read the initial question and the different responses and points of view. I would like to also share my point of view and tell you why I joined the Mormon Church.
I used to be Catholic, my entire family and relatives were all Catholics…but the Catholic environment did not answer many of my philosophical questions. My soul was not supportive of what I saw and what I felt.
At the age of 17 I started to become more intellectual and started think about the purpose of life, the origin of man and some other deep questions. The theology of the Catholic Church did not appeal and did not resonate with my soul. In my thinking and deep feeling there was only one true Church, but I did not know where that Church was.
I knew there were many Christian Churches, but their theology, even though all based on the Bible, were conflicting. On top of that there was the question of authority from God in my mind. I sensed that the true Church of God would have manifestations from Heaven, angels, celestial beings, new revelations. That is what I though in my mind as I read the scriptures. The interesting thing is that I had never heard of the Mormon Church until several years later. I investigated the Methodists, Spiritualism, Jehovah Witnesses, etc, till one day a friend of mine, who was an atheist by way, told me about Mormons. That is when my search started.
Well…this story can go on forever, but I will try to list some of the many reasons why I become a convert to the Mormon Church when I was 21 years old:
Beautiful Theology
Appearance of many celestial beings to many Mormons
Visit of God the Father and His son Jesus Christ to a young prophet
Visitation of old Prophets and Apostles of the Bible
Powerful personal revelation confirming Mormonism to be the only true church
Continuous personal inspiration and revelation as I practiced Mormonism
Mormon doctrines corroborated by the Bible, early fathers, etc
Prophets and Apostles as part of the Church
Mormon being the restored church of Jesus Christ
Continuous revelations from God
Continued cannon of scriptures
Priesthood (authority from God) restored and given to worthy man
Centered in Jesus Christ and in the family
Well…the list is long…but I think you get the idea.
