Because we are saved through Christ, 2 Corinthians 2:15 says we have the aroma of Christ, For we are to God the aroma of Christ among those who are being saved and those who are perishing. There is a distinct contrast in the aroma of something fully alive and something dying. Weather it is fruit, vegetables, plants, or animals, you can smell the freshness or lack thereof. It is the same difference in the aroma we are to God when we are saved and active believers through Christ.
