THis is my new favorite verse, what do you think it means?

beautiful imagery

But thanks be to God , who always leads us in triumphal procession in Christ and through us spreads everywhere the fragrance of the knowledge of him.
For we are to GOd the aroma of Christ among those who are being saved and those who are perishing. To the one we are the smell of death; to the other, the fragrance of life.
II corinthians 2:14-16
