Read: Matthew 7:1-6
Why do you see the speck that is in your brother's eye, but do not notice the log that is in your own eye? (Matthew 7:3 ESV)
It's so easy to see other people's problems. And yet, it can be really hard to have an honest sense of our own shortcomings. Often our own personal hang ups are a blind spot.
This is not a new problem. Jesus' disciples had the same problem. He thought it was a big enough issue that he addressed it in his famous Sermon on the Mount. Jesus point was that dealing with our own sin should take priority over confronting other people about theirs.
"Don't judge me" is an all-too-common phrase today. And while it is certainly grounded in a biblical truth it is usually pulled woefully out of context by someone trying to grant themselves free license to sanction whatever sinful deed they desire to commit. This was not the point Jesus was trying to make.
Jesus' point was that each of us should carefully measure our actions. We should take stock of our sin. We should pray that our transgressions would be revealed to us so that there would be no blind spots in our lives. We aren't to seek a life free from judgement, after all God is going to judge us all. Instead, we should realistically submit ourselves to the graceful judgement of Christ now so that we might be spared the justice of Christ later.
