Matt 7:1"Do not judge, or you too will be judged. 2For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.
Often we have a tendency to make assumptions about people based on a variety of external things: what they look like, what they are wearing, how they talk and the list goes on and on. Jesus warned us about judging a book by the cover. I have found many times that some of the best books had the simplest covers. Some of the most uniquely gifted people were wrapped in simplicity. Jesus was wrapped in simple clothes and laying on a bed of hay in a barn when he was introduced to the world. Imagine judging his future on his entry!
Don't forget that the way you judge others will be the very same way you are judged. How much you dish out determines how much gets into your dish!
Look deep into the heart of others. It will help you lest you judge too quickly.
