Here is an excerpt from Pastor Scott Gamels BLOG I go to on occassion( http://fiercegrace.wordpress.com/2009/03/03/beating-ourselves-up/) :
What’s sad is that some Christians tend to wear their self-administered beat downs like a badge of honor, and put them on bumper stickers, t-shirts, and into children’s ministry curriculum to try to recruit more followers to their system of works.
It’s safe to say that almost every Christian I know would declare that they are saved by grace – that there was nothing they could do to save themselves, or to earn their salvation. Yet many of them will turn around and try to live by works – as if the thing that could never save them will actually keep them saved.
And that’s the Christian version of self-flagellation…
We are saved by grace, and we live through Jesus’ life in us. “Christ in us” is our hope of glory, not our ability to do good or be good.
Below is the excerpt showing self flagellation that one religion engages in. Its not so different from the softer versions of this in Christianity.
