I notice one thing with people{I would say mostly the unsaved, but I've seen this with Christians too}is that they're "moody", and sometimes for almost no reason, they'll "snap at you, or "show their true colors,and give a selfish or arrogant reply if you say or ask something,Like , they just blurt out what they want ,not caring about the other person at all. Even amongst "friends" I 've seen this.{Family members too.}.And yes, Christians do this too.Like these people are making you a scapegoat for their own miserable feelings.They give in to their emotions,and just "have at you."{Only thinking of themselves.}Now, the origin of this kind of attitude?I think this "harsh tongue' is part of the fallen nature.Think so?
