Do religious people sacrifice a lot for church?

I remember one winter day when it was at least minus 10 degrees outside, I saw a crowd of female Christian teenagers walking around in skirts after a ceremony at church and I also remember seeing a woman at church, holding a baby in her arms while wearing very high heeled stilettos to attend church service on Sundays. I can’t imagine carrying a baby in stilettos and standing for that long. I also knew a church that had a ceremony exceeding 4 hours and nearly all the woman danced in heels the entire time.
