2 Corinthians 2:15-17 says this:
For we are to God the pleasing aroma of Christ among those who are being saved and those who are perishing. To the one we are an aroma that brings death; to the other, an aroma that brings life. And who is equal to such a task? Unlike so many, we do not peddle the word of God for profit. On the contrary, in Christ we speak before God with sincerity, as those sent from God.
