Battling Lust/Porn
I know there are a lot of posts about how to conquer "lust" on Christian subreddits. Most of these are actually about stopping porn addiction. I'd like to offer my commentary on what and why this is.
Now, before we begin, a couple of notes. We should all know what lust is from Matthew 5. I note that the wording "committed adultery with her already in his heart" is the main indicator. If your fantasy / imagination has you committing acts with a person that you are not authorized, such as anything with a married woman who isn't your wife, or sexuality and the precursors or what they look like naked for those you aren't married to, etc., if it is not authorized by God, it's lust to engage in this fantasy. If the thought just pops into your head, in my opinion, that's temptation, so push it away. No sin. But if you engage in it, fantasize about it, seek it, it's likely sin. But I like the sex addicts anonymous concept: if the glance lasts longer than 2 seconds, it's likely fantasy/lust.
Second, the Bible does NOT say masturbation is wrong. I would argue that if you are using it for stress relief, it is going to take over your life and become addiction. If you can't go on a trip and refrain for a week or more (like on a business trip or whatever), it might be problematic. But that's not my point. I don't recommend that married couples engage in separate masturbation, generally, but I'm just quickly glancing over this.
So back to the topic: why do we struggle with this? I'd offer several ideas. I don't follow (for instance) John Piper's absolutely awful, "if you would refrain from doing it if someone was holding a gun to your wife's head" etc. explanation. Piper shoots his mouth off regularly, and did so in this sermon quote that's on the internet. He clearly doesn't understand addiction. Addiction is trying anything to stop a behavior and you can't. Addiction rewires the brain.
First, I think we struggle because we have unmet needs. Genesis 1 has God saying it is not good for man to be alone. Now I am NOT saying this means the solution to lust/porn is to be married. In fact, the opposite: anyone who cannot stop watching porn is ineligible for marriage until they fix it. Why drag another person into your personal hell hole? God made you to be in relationships such as friendships, family, church, and ultimately if God wants it for you, marriage. That's why it seems to me that those who have the least social relationships are also usually the ones who struggle the most. See the Seven Desires of Every Heart book by Laaser & Laaser. We need healthy safe touch (not necessarily sexual). We need to feel chosen. To be loved. To be included. To be blessed. Denying our real emotional needs is madness, and no matter how stoic you think you are, you are lying to yourself if you deny that you have human emotional needs, no matter how small.
Second, I think we struggle because we are using porn/lust to deal with stress and possibly mental needs and illnesses. If we need to reduce our stress, we should exercise, meditate, read the Bible, pray, etc. Even with exercise, see Genesis 2: we were made to WORK the garden, not sit around. Psychological science has shown that those who are unemployed deal with tons of elevated anxiety and stress.
Third, it could signal a lack of relationship with God. Refusing to fill the spiritual needs in our lives (for Christians at least) can lead to a feeling of loneliness and alienation.
So recapping, psychological (stress), emotional (needs), spiritual (God), social (others). I am not saying it is only these 4 things. But I am asking you to consider these factors if you struggle. I am no expert but I'm 8 years sober from porn by the grace of God, soli Deo Gloria. I am simply blessed that God chose to pull me out of the septic tank I jumped into. And God wants to do this for you, too.
