How can a Christian reject part of the Bible and still call themselves a Christian?

You've been here three years?! Have I been gone for that long haha. Sorry, where are my manners. I'll give you my background briefly:

I can relate to what you're saying. I was raised a non-practising catholic (Catholicism... let'a be honest) and then in my late teens had a lightbulb moment with the faith and that in turn made me become a Born Again Christian. And I know what you mean about these feelings we get in the pit of our stomach, and the goosebumps we feel when it really hits us how good He is. But what is the root of all that? I mean, so far we've only accounted for our own psyche, and that's not saying a lot. We get people saying a lot of things right? So what I'm asking is, how do you know your feelings are causally connected to the Creator and not just a "feel good" mentality? I know you mentioned Paul, but him seeing a light in the sky isn't exactly an encounter. It's only just a notch higher than feeling warm inside.

Truth is I don't know 100% for sure. I'm making my choice based on where I'm being led. Like I said, I've strongly considered letting it go, but there's nothing else for me to go to. I think God has led me to where I am. By the way I was a practicing catholic most of my life and I let that go, so it's not a matter of me not being able to take that step to move on if I believe it's warranted.

If you yourself don't know how your belief is justified, then what have you been telling people here for three years? Until you can go from A to B through reason, all you have is an isolated case for what you believe in with no adequate argument to offer to anyone else.
