I hope you bear with me on this. I don’t drink alcohol, not because I’m against it, but because for me it’s like drinking medicine. You cannot tempt me with alcohol. Now, put a chocolate chip cookie out there and I’ll fight you for it (j/k). The point is, you cannot be tempted with that which you do not want. Women will never understand the power of a guy’s visual stimulation. So what’s the devil do? He puts every scantily clad girl out there on TV, internet, magazines (and I’m not talking porn here) but just in the supermarket. But here’s the thing, and it works, put it all under the blood. Sounds too spiritual I know, but you are a spiritual being and with repentance and the power of the Blood of Jesus Christ. How? Repentance is to change one’s mind and you’ve already done that because of the condemnation you feel. Now you just have to put the repentance into practice.
Do this practical exercise: take any magazine page and put it on a wall. Get some red paint and paint over it until you cannot read the page. Now that you have this visual process in your mind, recall every inappropriate image you can remember and paint over it in your mind – the “paint” being the Blood of Jesus. Claim in the Name of Jesus to be gone. This will work if you believe. Here’s why it works.
All throughout the scriptures the word says to guard against your thoughts. Jesus said this:
Matthew 5:28 (KJV)
But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
Jesus equates the sin of adultery with looking on a woman with lust. How so? Well, you see a pretty girl, and in an instance, your MIND is racing scenarios of what she might look like nude, or in compromising positions. This is done on the movie screen of your mind. This causes all kinds of physical reactions, hormonal increases, releasing addictive endorphins … These fantasies rewire your brain so that you can produce these endorphins every time you fantasize and because of that you become more addictive, creating a vicious circle of sin, condemnation, frustration, repentance, sin, condemnation, frustration, repentance, sin, condemnation, frustration, repentance… So why doesn’t the repentance stick? We’re not warring correctly. We can’t do it in the flesh. Read this slowly:
2 Corinthians 10:3-6 (KJV)
For though we walk in the flesh, we do not war after the flesh: (For the weapons of our warfare [are] not carnal, but mighty through God to the pulling down of strong holds) ; Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ; And having in a readiness to revenge all disobedience, when your obedience is fulfilled.
Your strong-hold (and 99.9999999% of all guys) is this issue of lust in today’s loose society. You must cast down imaginations and every high thought and bring it into captivity (through the blood of Jesus). And when, not if, when the temptations arise, you close your eyes, paint the Blood of Jesus over it and claim the power of His obedience. This is having an active mind and not a passive mind. An active mind is controlling the thoughts you have, focusing all the time on the task at hand. This is why the word says to meditate on the word day and night, why to have a song in your heart, praying without ceasing, they are ways to keep your mind active and focusing on Jesus. This is how you first, submit to God, and resist the devil.
James 4:7-8 (KJV)
Submit yourselves therefore to God. Resist the devil, and he will flee from you. Draw nigh to God, and he will draw nigh to you. Cleanse [your] hands, [ye] sinners; and purify [your] hearts, [ye] double minded.
You’re struggling, like we all do, because you’ve not dealt with this sin in your life, and until you do, you’ll always remain in this vicious circle until you either win or surrender and stop trying, searing your conscience with a hot iron. So read these verses and learn what God is trying to say:
Philippians 4:7-9 (KJV)
And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus. Finally, brethren, whatsoever things are true, whatsoever things [are] honest, whatsoever things [are] just, whatsoever things [are] pure, whatsoever things [are] lovely, whatsoever things [are] of good report; if [there be] any virtue, and if [there be] any praise, think on these things. Those things, which ye have both learned, and received, and heard, and seen in me, do: and the God of peace shall be with you.
The war you’re going through is the same for everyone, some with alcohol, other with feelings of inadequacies and binging on ice cream until they’re 300 lbs with diabetes. Everyone has a vice, and these tendencies are the meaning to this verse:
Exodus 34:7 (KJV)
Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear [the guilty]; visiting the iniquity of the fathers upon the children, and upon the children’s children, unto the third and to the fourth [generation].
Since our parents didn’t deal with their sins, the tendencies towards one or another are in our DNA, scientists have proven this. They’ve also proven that we can rewrite our DNA by doing just what the word of God says to do, have an active mind. Now this only works because you’re a Christian through the Blood of Jesus. There are indeed benefits to the lost too, but they’ll never overcome. So take comfort, it is indeed in your mind just like Paul says:
Romans 7:21-25 (KJV)
I find then a law, that, when I would do good, evil is present with me. For I delight in the law of God after the inward man: But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.O wretched man that I am! who shall deliver me from the body of this death? I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
2 Timothy 1:7 (KJV)
For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.
I pray this helps, it did me 
that’s why I know it works!
