The issue is that I feel, on a deep level, that Christianity is true.

In a kind of Disney movie/believe in yourself/do what you feel is right, kind of way? I'd just go right ahead and suppress that feeling. Seriously. Things don't become more likely because you have a deep feeling that they're true. Lots of people have deep level feelings about lots of things*.The great thing is that if you suppress those feelings, and God does turn out to exist, being rational about it will lead you to the correct beliefs anyway.

*I have a constant feeling that pacifism is always the right course, and that I should never use violence for anything. But I suppress this feeling because it isn't actually correct.
