Flowers fall off and their aroma disappears, but the aroma of goodness coming from within one's heart is seldom forgotten because it gives impression, influence and changes to the people around him. The strongest aroma comes from those who resemble our good Jesus Christ. For this aroma, you have to meditate on God's word day and night counting it as so valuable, pray in the Holy Spirit, and practice goodness in love.
"For we are a fragrance of Christ to God among those who are being saved and among those who are perishing." (2 Corinthians 2:15)
