Dead flies

As dead flies give perfume a bad smell, so a little folly outweighs wisdom and honor. (Ecclesiastes 10:1)

In a car lot on the outskirts of Kabul, three saloon cars and a truck lay abandoned due a numerical curse that has swept Afghanistan. A strange phenomenon that equates the number "39" with prostitution has become a nightmare for the car industry, as buyers avoid car licence plates having the dreaded number for fear of being ostracised. The car yard's owner complained that it was no longer just a social issue; it was an economic issue. "It has been months and no-one is buying them," he said, pointing at the white, black and blue sedans. "39" got its bad reputation through an erstwhile pimp who was often identified by the number on his car plates as he drove around Herat, the western city. The man's shady image and illicit business meant that the number became associated with immorality. The tale spread to other Afghan cities and the curse was born. Now anyone seen travelling around in a vehicle with a "39" licence plate is in danger of being linked to the illicit sex industry.

The danger of a believer being involved in sexual immorality is that it will have lasting disastrous consequences. It would be like a curse, with unbelievers and other believer's always looking at that person with judgemental eyes and with suspicion even though the person repents.

The Bible speaks strongly against this sin and advices extreme restraint.
Flee from sexual immorality. All other sins a man commits are outside his body, but he who sins sexually sins against his own body. (1 Corinthians 6:18)
Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed, which is idolatry. (Colossians 3:5)
It is God's will that you should be sanctified: that you should avoid sexual immorality. (1 Thessalonians 4:3)

Always best to heed what the Bible advises and advocate restraint, rather than be a fool.
