But thanks be to God, who always leads us in triumph in Christ and manifests through us the odor of knowledge of him in every place. For we are the aroma of Christ for God among those who are being saved and among those who are perishing, to the latter an odor of death that leads to death, to the former an odor of life that leads to life. Who is qualified for this? For we are not like the many who trade on the word of God; but as out of sincerity, indeed as from God and in the presence of God, we speak in Christ.
II Corinthians 2:14-17
