Do devout Christians ever act overly polite to their detriment in life? [Spirituality & Religion]

You misspelled "Canadians"

It is not to our own detriment. It is eternal perspective. It is living with eternity in mind instead of this short vapor of a life. If anyone is going to know that God is love, joy, and peace, then His people need to reflect Him by showing what love, joy, and peace He has given to them. IF it is of our own effort and not something naturally stirred within us then it is not genuine and perhaps that is why you only see an "ass-kisser". Perhaps he is, or perhaps it is natural to him now.

Can you define devout? Im a jesus follower.
That usually means im a christian, but please dont associate me with hypocrites who damn everyone but themselves. Among other things.

I know a devout Christian who's a people-pleaser and ass-kisser, but I don't think Jesus went around people pleasing and ass-kissing. I think my devout Christian friend is overly polite to people to his own detriment.

I can't say I have. Guess I need to live a little longer, heh.

Rarely. We are humans and humans have a fight or flee mechanism. Your opinion is not very important once a person triggers your body to act
