The difference to me is the authority factor. It's not just God's gift, it's God's tools.

If you sing or paint well, it's a beautiful gift meant to be shared with others. People can choose to love your work or think it stinks. They can choose to buy what you're selling or keep on browsing.

Selling God just seems weird to me. What if you're not satisfied with God? I can just hear people now. Hey - What happened!?! I paid GOOD money to know my future and get into Heaven!

My father would have whooped my butt if I ever sold his precious tools, lol.
