Prejudice is one of the great plagues of the modern world. People can and will find anything to judge people on. I must confess that I am guilty of this. It's easy, when you think about it. "He dresses this way and listens to this type of music, so he must be like this." "She drives this type of car and wears this brand of clothing, so she must make this much money."
It goes beyond that, though. We have moved beyond the level of judging a person to a point where we try to decide the status of their slavation. "Well, no one who comes form this background could possibly be a Christian." "No one who has made this mistake will ever be saved." But remember what Paul says: God is ultimate Judge. He will judge based on truth and the forgiveness that Christ brought to Earth.
"Jesus loved the outcasts. He loves the ones the world just loves to hate. And as long as there's a heaven, there'll be a failure to excommunicate."- Relient K
