Kaylee, so we have a few problems on the surface, some which are now unfortunately harder to solve than the query letter (which I would still advise you to post).
Your greatest obstacle is your word count. There is simply no way you will get an agent with a book that long. Heck anything over 120 000 is considered way too long let alone into the 200k's. There are the rarest of rare examples of a first time author getting published with a first novel this long, but they are so rare that I fear even mentioning it here as a means of giving you hope. Honestly, hon, it's just too long.
Next your genre. This is a big deal because the Christian market is a very different market from mainstream. If your book deals in Christian themes, and the moral is something like the goodness of god, or bringing god into your life etc, then no matter what else your story may be, it is Christian fiction, possible you can call it a humorous Christian fantasy. However if your book is more of an allegory of a biblical tale that is not an obvious message story to people about the Christian faith, if it uses tried and tested tales in that regard, the apocalypse and how humans handle it, vs the apocalypse and how the righteous are rewarded and the sinners punished, then you may have a humorous fantasy on your hands, possibly satirical (I'm not sure what kind of humour you are using, you didn't specify)?
But truly, your biggest obstacle is your word count. I also worry that you refer to your book as your baby. Certainly books we write are near and dear to us, but we also have to be brutal with them, tear them to shreds, get rid of characters we adore . . . we have to be pragmatic as authors as well. We can't cradle our books and protect them as if they are living things. They aren't. They are words on a page telling a story in the best way you can. And sometimes we can't always see the best way and it takes someone else telling us what we have to do to fix it.
One of the biggest mistakes first time authors make is writing too much. Believe it or not the mark of a professional is someone who can be concise, clear, and still keep poetry in the text. The more you cut out of your book I am sure you will find the tighter, the better, the more like a "real book" it will be. I come from personal experience. I had a novel at 97 000 words and was told to cut 10 000 (nothing compared to the edits you have to do, but as far as a ratio goes, it was still considerable). I did it, and not by cutting a single scene, but rather paragraphs, even individual words. And the final result, well people couldn't actually tell what I had cut, they only knew that the work read so much better, was so much stronger.
Not nice to hear, but it is the truth. You really are going to have to cut that story of yours down to a manageable size. If possible you could make it into two books, providing they can also stand on their own. But without even reading your query, I know the problem, at least one of them, and this is it.
So it is time to take a long hard look at your baby. And bring out the scissors.
