I'm not Christian - but I suggest you change the domain name, it is insulting to good Christians. It's ok for you to be an athist, and for me not to be Christian, but why go around annoying nice people?
To comment on the site design: I think the content/news/exits buttons are proportionally too big- they don't seem to match the rest of the design. Additionally, I've always hating embedded scrolling bars... that's just me though.
Dealing with the religious issue: I can't help but wonder how many customers you could lose because of the title when the majority of people believe in a God. Christian or not, most religions at least acknowledge Jesus as a great teacher.
Also, I'm always curious about so-called atheists preoccupation with God and religion. Always seems to be built up frustration. If there's no God, who are you mad at?
Your design and style is impressive, as is your portfolio ("work" link). I tend to agree with the other posters in that you may offend some simply by the name of your domain, but I'm sure you already know that.
