'Impurity' in the Bible

For this reason, in accordance with their own depraved cravings, God gave them up to uncleanness, allowing them to dishonour their bodies among themselves with impurity.

your human infirmity leads me to employ these familiar figures--and just as you once surrendered your faculties into bondage to Impurity and ever-increasing disregard of Law, so you must now surrender them into bondage to Righteousness ever advancing towards perfect holiness.
