I am a Christian although I subscribe to no particular denomination and I am a former Atheist. I was raised in a very strict religious family and had a period in my life where I ultimately rejected the notion of a God altogether. However, I have returned to my faith in recent years and I consider myself immensely spiritual. A life without God for me was a bleak one and my belief in Christ gives me hope and happiness. I believe in being a kind person and I believe that living to help other individuals is my duty as a human being. Furthermore, I believe that all of God's creations are special and worthy of respect. My religious views are also somewhat unorthodox, as I do not believe in hell or Satan or any inherent "force of evil", nor do I believe that only adherents of Christianity ascend to heaven. I think the gates of heaven are open to everyone and a lack of religion doesn't exclude one from the afterlife.
With that being said I have no way of proving if God exists for I truly don't know. My perspective is that if God is real then I will serve him and if God isn't, what have I got to lose? I must admit I find religious debates somewhat ridiculous because nobody truly knows and I think the question on the existence of a higher power will remain unanswered, which doesn't bother me. While I have no insecurity regarding my Christian faith, I consider myself to be very open-minded about other people's beliefs.
