Why is my credit card being denied?

Are you sure it is a Credit card - or is it a Debit card ? Debit cards are not normally taken as a means of payment by Apple.

Another reason could be that the Applid associated with your payment is not registered in the same country as the card or billing address.

YYes I'm sure. I know it's God as well.

Well if your card is in God's name, that could be your problem. Get one in your own name. 😉

Seriously, you'll need to contact the iTunes Store and find out exactly what the problem is. Use the Contact Us link at the bottom right of every page for information on how to do that.
