I was born with believeing parents, so automatically, I assumed that there was a God because my parents told me so.
When I was young, I prayed before going to bed and said thank-you for all that I had.
Later in life, I realized that what I had came from my parents, not necessarily God.
Today, I still believe in God, but I wonder if he cares.
There is something worse than no God
It's a God that doesn't care and doesn't answer prayers.
When you look at the world as a whole, and see all the suffereing and injustice, you don't ask yourself if there is a God, you just wonder if he CARES.
