Isaiah 58:9

Then you will call, and the Lord will answer; you will cry for help, and He will say, “Here I am.” If you take away from your midst the yoke (of oppression), the finger pointed in scorn (toward the oppressed or the godly), and (every form of) wicked (sinful, unjust) speech.

If we are to be a church without spot or wrinkle, we must start judging ourselves. When we walk according to the Bible and guiding of the Holy Spirit we will recognize error in our lives. Death and life are in the power of our tongues, and we should consistently practice controlling our thoughts and our speech.
