Lots of religious people, not only member of the Church of Jesus Christ of Latter-Day Saints come on here. So this is the perfect spot. I think the others covered this pretty darn well, but I wanted to say a lot of people claim we come up with these feelings because we believe it or want it to be true. I don't completely believe that and if those who do believe that, oh well.
I don't think it can be that way. There have been too many moments where I was just sitting thinking about literally nothing and I've felt the spirit. Driving down the road I've been saved from serious car accidents by little promptings telling me to slow down or get to the other side of the road a bit more. I've missed deer by a few feet and a car coming the other way because I listened to those little feelings. There is something out there. A God. And from my experience I've felt my religion is true. From study and "soul-searching". I suggest you read the Bible a bit or the Book of Mormon (Another Testament of Jesus Christ) and pray to see what you feel.
If you want any information on any part of religion or the church this thread tries to share. We are here to answer. (Sorry. I'm practicing my missionary speech )
