I didn’t find anything offensive in it and even if I did would it matter? If this is something you are passionate about, if this is something that is true for you then you should keep at it. You can’t please everyone and religion is one of the few topics that always gets people fired up. There will always be an extremist out there condemning you to hell, don’t take it personally.
I did find the site a little confusing to navigate and I think adding an “about” section to the page would be helpful.
