Sin is cosmic treason. Sin is treason against a perfectly pure Sovereign. It is an act of supreme ingratitude toward the One to whom we owe everything, to the One who has given us life itself. Have you ever considered the deeper implications of the slightest sin, of the most minute peccadillo? We are saying no to the righteousness of God. We are saying, "God, Your law is not good. My judgment is better than Yours. Your authority does not apply to me. I am above and beyond Your jurisdiction. I have the right to do what I want to do, not what You command me to do."
The slightest sin is an act of defiance against cosmic authority. It is a revolutionary act, a rebellious act in which we are setting ourselves in opposition to the One to whom we owe everything. It is an insult to His holiness. We become false witnesses to God. When we sin as the image bearers of God, we are saying to the whole creation, to all of nature under our dominion, to the birds of the air and the beasts of the field: "This is how God is. This is how your Creator behaves. Look in this mirror; look at us, and you will see the character of the Almighty." We say to the world, "God is covetous; God is ruthless; God is bitter; God is a murderer, a thief, a slanderer, an adulterer. God is all of these things that we are doing."
