For those porn addicts, the bible is pretty clear that we are to flee from sexual immorality, from the porneia that can so easily settle into our hearts. I think the basic video that starts off the Covenant Eyes 40-Day Challenge (http://www.covenanteyes.com/challenge/) is very astute that you can't just stop there. They prescribe the following:
1. Run FROM
2. Run TO
3. Run WITH
First, you should flee sexual immorality. This particular sin joins the Holy Spirit to the body of a harlot. If you think that avoiding full coitus will keep you from dragging the Holy Spirit through your sinful acts, think again. Your body's chemical reactions are virtually the same in reaction to porn as they are with a full sexual act with a real woman. And if you think that you do not grieve the indwealt Holy Spirit with your eyes and hands when you perform sexual acts with yourself, you are deceiving yourself altogether. So, run AWAY from sin. Get away from the computer, out of the house if you need to. Create the hard-line boundaries in your life, no matter how important the object that you may need to cut from your life... "If your right hand should cause you to sin, cut it off". Install filters, or at least accountability software (Covenant Eyes is great, and there is a link to it in this blog). This is where victory begins, but you cannot merely empty a household of demons and not expect them to come back stronger than before. Your household, your temple of the Holy Spirit, needs to become a stronghold for God. That is accomplished in the next steps...
Second, you should run TO God. He is our salvation, our rock, our mighty fortress, and he will give us shelter from the storm and protection from ourselves and the great tormentor. We should fall on our faces before Him and beg Him for strength to resist temptation, for every temptation comes with a way out, and He can help us. Also, run to accountability partners, other strong believers that can help you get through these difficult moments. Whatever you do, get your mind off of the preoccupation of pleasuring yourself, and work to serve God and to serve others for the sake of God's kingdom and glory. Find a way to accomplish the very thing for which God made us - to glorify Him, and to enjoy Him forever. Find practical ways to get out of your isolation and serve others - widows and orphans in their distress, friends that might need you in their hour of need, or your family that very well may need any number of things done (you might have to do dishes - gasp!).
Third, you should run WITH God. True strength is not found by just avoiding sin, and not by just falling on your face before God, but in communing with and dwelling with God. God equips us with the full armor described in Ephesians 5, all elements of which are attributes that are purely provided by God; only through a full realization and full meditation of all of these attributes can we attain a renewing of our minds. Salvation, Righteousness, Truth, the Gospel, Faith, and the Word of God. These should all be ready in our arsenal as we go about our day. Find ways to pray for those who are close to you, and those that you meet for whom God gives you a heart. Meditate on God's word. Bring God into every situation and ask Him to show you how to glorify Him as you go about your business, as you shop, as you socialize, as you do everything. Pray without ceasing. Treasure His word in your heart. But most of all, ready yourself for battle.
