1 Samuel 16:7
"Stop judging others, and you will not be judged. For others will treat you as you treat them. Whatever measure you use in judging others, it will be used to measure how you are judged. And why worry about a speck in your friend's eye when you have a log in your own? How can you think of saying, `Friend, let me help you get rid of that speck in your eye,' when you can't see past the log in your own eye? Hypocrite! First get rid of the log from your own eye, then perhaps you will see well enough to deal with the speck in your friend's eye."
You know people who do that kind of thing, right? And many of us – maybe most of us - know what it’s like to be on the receiving end of people who judge others. Jesus says that we need to be careful. Whether it has to do with people’s actions, or lifestyle, or children or weaknesses or sins or worship preferences. Be careful, Jesus says. Jesus knows that we have a tendency to bring out the faults of others and down play our own sins. We tend to have a better view of our own opinions and a more negative view of anyone who thinks differently.
Jesus calls us to work with each other, speaking the truth in love and encourage one another. We have a responsibility for each other, and if we see sin we have to deal with it – Jesus says that too. But it’s our attitude, our motivation... it is the condition of our heart that really determines if we are building and discipling in love for the other person, or if we are just being judgmental.
My daughters pastor brought up a good point when he was saying that when we look at someone who looks differently or are doing something that we feel is wrong, we don't know personally what they are going through and we should not judge someone else based on what we observe only. For many people judging others are their favorite past time. The prettiest girl, the jock, tattoos, too fat/thin, not dressed appropriately, the wealthy or other favorite people, often become the targets of hateful tongues and thoughts. I guess you would not even have to be in a favored position to have others "bad mouth" you. It is very easy to take part in judging those around us if they do not come up to our expectations.
