I'm mormon and I'm going to be leaving home to serve an lds mission in less than a month. Personally, I've found that as I've gone to church every week, read the scriptures, and prayed every day, I've felt the Holy Spirit giving me more insight into what the verses of scripture mean. After years of seeing God's hand in my life, I can testify that I know that Jesus Christ is my Saviour, I know The Book of Mormon is the true word of God, and I know that The Church of Jesus Christ of Latter Day Saints contains the full restored gospel of Jesus Christ. I know that God continues to give revelation to His prophets today.
I'm not trying to shut you down ooBrony, I just thought I'd share my personal experience with the church.
