I was talking to a friend the other day, and he was asking me about my faith. showing that he was interested in the way the i choose to live my live, i gladly started to explain the relationship the i have with my Jesus. I began to explain the reason why I am the way that i am, and the reason why I believe in a God the you can not see. I explain the i believe in Jesus and how he has saved me and given me a life that nothing else could ever compare too. This friend grew up a Catholic, so he understood the fact that Jesus died on the cross for me. But he doesn't really believe that there is a God. My question to anyone who reads this is, do you believe there is something else out there, or do you think we just kinda happened?
