Is it possible to watch pornography and not sin? In any way?
It is difficult to come up with an example of a legitimate reason for viewing pornography since the reason it exists is to stimulate lust in the viewers. "For this is the will of God, your sanctification; that is, that you abstain from sexual immorality; that each of you know how to possess his own vessel in sanctification and honor, not in lustful passion, like the Gentiles who do not know God" (I Thessalonians 4:3-5). To obtain this, it glorifies improper sexual relationships of every sort. "And although they know the ordinance of God, that those who practice such things are worthy of death, they not only do the same, but also give hearty approval to those who practice them" (Romans 1:32).
