The stench just doesn’t wash off…. you have been skunked. 
Sin stinks and it will follow you. I remember standing in line at Lowe’s behind a man and the stench was so bad I had to back up. I could not identify the smell. The Lord spoke to me and said this is a smell of sexual immorality, he is into pornography. I immediately started praying for the man. 

Imagine how horrified that man would have been if he knew his sin was known by the aroma he was carrying around.

There is a pleasing aroma to the Lord, “For we are to God the pleasing aroma of Christ among those who are being saved and those who are perishing. 2 Corinthians 2:15

Remain in Christ, in Him there is no sin, “And you know that He was manifested to take away our sins, and in Him there is no sin.” 1 John 3:5
