It's so tempting when we are doing things right (whatever that "thing" might be) to quickly jump from being satisfied that we are walking on the right path (and conveniently forgetting that it is only through God and by His grace that we CAN walk) to noticing those around you with disgust or disdain, who from your point of view appear to be off that righteous path.
Some words of wisdom from C.S. Lewis...
"Whenever we find that our religious life is making us feel that we are good, above all that we are better than someone else, I think we may be sure that we are being acted on - not by God, but by the devil."
He goes on to say, "The real test of being in the presence of God is that you either forget about yourself altogether, or see yourself as a small, dirty object."
(from Mere Christianity)
Jesus said, "Healthy people don't need a doctor--sick people do. I have come to call not those who think they are righteous, but those who know they are sinners."
So I think it would be prudent for all Christians to Use a little caution...
