Is Christianity Illogical?

[Mystic]

I think I'm going to try to help our new friend here:

It's logically possible God exists.
It's logically possible this God sends a religion.
It's logically possible there will be evidence for this religion.
It's logically possible then to have well supported faith in this religion.
Therefore faith in a religion is not necessarily illogical, as far as logical possibilities go.
Therefore this proves faith in religion can be logical.

Now moving away from faith, the things to discuss.

1) Is there proof God exists (I do believe there is, but Atheists don't, so might want to work on this step).
2) Is there good reasons to believe God sent a religion? (As a Deist, I believe there is possible good reasons to not send a religion, and I would be happy to discuss those with you)
3) Is there such evidence for any religion? (ie. Muslims argue Quran being unique type of literature is such evidence, what is your evidence?)
4) While faith in a religion is not necessarily illogical, can you prove then in the real world, faith in a religion is not illogical? (ie. you might want to expand on the holy spirit or something)
