Hell to the YES.
I've been reading Real Life Preacher's archives over the last few days and something that he wrote just jumped out at me...and not because he wrote it in italics. He's talking about when his daughter asked if God really exists.
No one knows for sure if God exists. Sometimes I wish we COULD know for sure, but it's one of those things that cannot be known in the same way we know that Zebras exist.
That's okay though, because whether or not God exists is not the most important question. What's really important is how you choose to live. You may choose to believe in God and live accordingly. Or you may choose to believe that there is no God. This kind of belief is a choice you make and a commitment of your life.
You will have to choose. And you will find the answers you need in the living of the life you choose.
