2 Corinthians 2:12-17
12 When I came to Troas to preach the gospel of Christ, even though a door was opened for me in the Lord, 13 my spirit was not at rest because I did not find my brother Titus there. So I took leave of them and went on to Macedonia.
14 But thanks be to God, who in Christ always leads us in triumphal procession, and through us spreads the fragrance of the knowledge of him everywhere. 15 For we are the aroma of Christ to God among those who are being saved and among those who are perishing, 16 to one a fragrance from death to death, to the other a fragrance from life to life. Who is sufficient for these things? 17 For we are not, like so many, peddlers of God's word, but as men of sincerity, as commissioned by God, in the sight of God we speak in Christ. (ESV)
