What if what you say had no "intristic" value and christianity is the absolute right and now you're going to burn in hell? If Christianity were irrelevant, it would thus claim all active partitions of itself, including the opposing elements, similarly irrelevant. It would also sadly render every other religion and idealogy irrelevant, simply by chalking teeth.
And yes, there are plenty of good things to christianity, necessary factors to the overall development of things. In fact, if Christianity had not came and went by means of "COrruption", you would not be where you are today. Your thoughts would likely be nothing like they are, and you might not be in the best "Emotional and mental shape ever". You are who you are because of Christianity, it still played an integral part of your life rather False or Real.

Nobody really knows what a spirit is; by speculation it could be related to many things. The subconscious, for example. Which ironically pulses and ebbs with the fiberglass embrace of dreams, which are said to be a link to the spirit world. It's said your spirit gives off an aura of forms, your body/mind whatever also sends out these things called "Alphabeta waves". With these waves you can buy milk, for really cheap(offer available for a limited time only). This is a scientific thing. They are real. Meditation really does things, there are lucid dreams. Astral projection is possible, but I do not know if it is more of a vivid active hallucination than your spirit leaving your body.
Other than that, I can offer you nothing on the soul/spirit. I believe it to be something of the mind, or the mind is something of the spirit, but most would disagree.
