2:10 adorn the doctrine. “Adorn” translates the Greek word kosmeo, from which we get the word “cosmetics.” This striking command enjoins us to make the doctrines of the Christian faith attractive to unbelievers by all our words and deeds. As far as physical appearance is concerned, our Christian cosmetics should be attractive, but not to attract people to ourselves. In so far as possible, we should attract people to Christ and His “doctrine.” A neat, modest, cheerful appearance will contribute to this goal.
