Carson on our propensity for hypocrisy. Matthew 6:1

“We human beings are a strange lot. We hear high moral injunctions and glimpse just a little the genuine beauty of perfect holiness, and then prostitute the vision by dreaming about the way others would hold us in high esteem if we were like that. The demand for genuine perfection loses itself in the lesser goal of external piety; the goal of pleasing the Father is traded for its pygmy cousin, the goal of pleasing man. It almost seems as if the greater the demand for holiness, the greater the opportunity for hypocrisy.”
