Incense was scattered along the parade route of a victorious Roman general, and people received it in two ways. For the captives heading to the arena and death, it smelled like death and doom. For the victors, it was a life-giving perfume. This is similar to those who share the good news about Jesus. It either leads to eternal life or seals the fate of those who reject it (compare 1 Corinthians 1:18).
