Proverbs six is a remarkable description of evil. And evil has a body: eyes, tongues, hands, and feet. Solomon says that these parts function as diabolical agents. The haughty eyes descend to the tongue, and to the hands, and downward. This confirms the theological aspect of the down-wardness of human sin. Satan is a murderer and a liar, so too, those who follow him use their bodies to bring forth his purposes by lying and shedding innocent blood.
We need to consider our sins in light of the seriousness God gives to our sins. Our sins are dreadful in the eyes of God. When we consider the sin of the eyes, the sin of the tongue, and the sin of the hands, consider also that those sins are detestable in the eyes of God, that God curses them with His tongue, and that He does not pour blessings with His hands upon those who dwell in them.
