Correct...it can be a blurry line at times because as you stated we its easy to fall into that trap of "well at least I'm not like that person" or it appears there is no fruit there. For that reason we have to be vigilant not to be led astray, but also to make sure we allow our other Christian brothers and sisters grace (for those that truly repent), just like Jesus extended to us.

Unfortunately many abuse grace, and use it as an excuse to live in the darkness. This is why it is so important to know His Word; the only source of truth so we may discern good from evil and truly understand the concept of judging them by their fruit and as Jesus said, we recognize His voice.
