But the things that come out of the mouth come from the heart, and these make a man "unclean." For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false testimony, slander. Matthew 15:18-19
Another question to put to yourself is, "Do I have any habits I am ashamed to let anybody know I have? Have I any personal habits that I am ashamed of? Do I hide something when the pastor is coming? If everything were known in the church about how I lived, would I go back to church?" You can dodge this, twist it around and answer evasively, but the snow will lie on your heart. If you answer God honestly and go to work to get rid of it and clean it up, springtime will come for you. Then ask yourself, "Is my speech clean?" One of the most shocking things in the church is the dirty-mouthed Christian who always walks on the borderline.
