D&C 63 has some blunt doctrine. In it, the Lord states
D&C 63:19 And now behold, I, the Lord, say unto you that ye are not justified, because these things are among you.
The list of "these things" includes looking after a woman to lust after her and it also includes liars.
We must pay heed to this double condemnation of pornography, for the Lord concludes "I, the Lord, say unto you that ye are not justified, because these things are among you."
What do we care about more than whether the Lord justifies his church?
We must make sure that these things are not among us. We must not allow them to linger among under the label of "addiction". The scriptures are quite plain. If they are doing these things and will not stop then they should not be numbered among us, or the Lord will not justify his church.
Looking at pornography "less frequently" or "feeling bad" but continuing to do so is no more repentance than committing adultery "less frequently" or "feeling bad" but continuing to do so. The requirement is that we repent and forsake them. We must follow the scriptural injuction and prefer to cut off those who are liars or who look upon a woman to lust after her if they do not cease to do such things or we will not be justified before the lord as a church. And what could be more concerning to us than that?
