I am a member of the The Church of Jesus Christ of Latter Day Saints (LDS). I've lived in Utah most of my life, and LDS is the religion I was born into. My parents never did force me to go to church though, it was by my choice that I continued to attend.
I've always known in my heart that Jesus Christ is real, and that he does love me. That without him there is no hope for us. So the obvious choice of religion for me was Christianity.
The reason that kept me believing in LDS when I was younger was that not only the fact that Jesus Christ is the center of our religion, we also believe in modern day scriptures, prophets and apostles who are living oracles of God. The concept was simple to me, if God called prophets for thousands of years, and he kept giving new scriptures for thousands of years, why would he all of a suddenly stop during the second century AD. The first century church was led by apostles and prophets, They were the foundation of the church with Jesus Christ has the chief corner stone. (Eph. 2:20) The way how I saw it, (and still do) is, that you CAN NOT have a doctrinally sound religion, if you do not have prophets (Amos 3:7) or apostles acting as LIVING ORACLES of God.
As I got older, I realized that I needed to find out for sure if my religion was actually true, or just a fake. Was The Book of Mormon really scripture? Was Joseph Smith a true prophet, or a fake? Is our current prophet, President Gordon B. Hinkley really a living prophet of God? So I did the studying and praying. I did eventually receiving an answer from on high. I did receive an answer to my prayers. An answer that came so strongly to me, that I could not deny it. The answer was that it is all true, and this is where I need to be.
That is why I am a member of my current faith. And I will say without hesitation, that I know that I am a member of the True Church of Jesus Christ.
