How could be be sanctified? By avoiding sexual immorality.

It is better to seek the pain of heaven than the pleasure of hell.

To defile your body is to quench the Holy Spirit.

The acts of the flesh are obvious: sexual immorality, impurity, and debauchery. Galatians 5:19

Sanctification leads to renewal of the spirit.

The sinful desire of the flesh leads to uncleanness, sexual immorality, and sensuality.
