'Indecency' in the Bible
Now the practices of the sinful nature are clearly evident: they are sexual immorality, impurity, sensuality (total irresponsibility, lack of self-control),
Because they are callous, they have given themselves over to indecency for the practice of every kind of impurity with greediness.
Let there be no filthiness and silly talk, or coarse [obscene or vulgar] joking, because such things are not appropriate [for believers]; but instead speak of your thankfulness [to God].
For there are certain men who crept in secretly, even those who were long ago written about for this condemnation: ungodly men, turning the grace of our God into indecency, and denying our only Master, God, and Lord, Jesus Christ.
