Christianity was all about Jesus dying painfully and the religion promoted the notion that followers would do well to imitate him literally.
Yes Christianity is a religion that promotes martyrdom and self-sacrifice. We had this a lot in the memorial talk. If Jesus had those six-inch nails hammered into his hands and died an agonising death for you, the least you can do is pioneer, go to bethel, sell your house for the kingdom and so on.
The way I feel now is, self-sacrifice is all very well but what's in it for me?
