Godless

So I am reading this book called 'Godless'. It's about this boy who makes up his own religion because he is sick of his parent's (whom are Catholic) His god of his religion is the water tower of the town. He says: "Water from that tower was piped to every home and business for miles around. It kept us alive. That was when I came up with the idea of the water tower being God"
As soon as I read that sentence, I thought about how much it related to everyone including me.
Grace is like water, it's piped to everyone.
God keeps us alive. Eternally.
Now the whole idea of the water tower being God what in our lives do we make our God? I know I would like to say "I don't make anything my God" but then I would be lying.
Many of us could say friends, the computer, parties, video games, movies, shopping and the list could go on. And half the time we don't realize what we are doing.
So is this boy in the book outrageous and needs to be locked in a room with a Bible? No. It is sin. And we all have sinned, so why should one person be condemned for their sin and all of us just sit around and watch? That's not how it works.
I honestly don't want anyone to think that I am preaching right now... But basically what is on my mind is that, I need to clean up my act. I shouldn't be making my guitar hero, God.
A sacrifice was made so I could have a relationship with God...why am I wasting it?
