Christianity Question?

I have always been a believer in a higher power, never brought up in a religious family, have been to clairvoyants and am quite intuitive myself as well as being a lovely person. I know people who are "christians" but do the most obsurd and judgemental things ever!!! and then preach to me about the lord and me becoming saved etc....why do they impose this on people especially when they are talkn through"god"....??? Confused.!
