"There is therefore now NO CONDEMNATION for those who are in Christ Jesus"

You need to focus on this verse.

Demons are the exact opposite. They want to fill you with Condemnation and want you to think it is hopeless. Demons are the ones who fill you with Lust in the first place. So in a way it is not you who is sinning, it is them. God will Honor the fact that you Hate your sin. That is all he wants. Jesus will help you overcome.

"The Sacrifices of God are a Broken and a Contrite heart"

It seems to me like you have that.

Even Paul had to Battle his Flesh and proclaimed "Oh wretched man that I am".

"No sin has overtaken you than what is common to man"

Porn is such a Huge Problem and such a common problem even in the Church.

I would recommend watching Testimonies on Youtube of people who have been delivered from Witchcraft and Porn and all kinds of sin.

Don't focus on 'not sinning'.

Focus on the Jesus and how he wants to help you and the Holy Spirit. The only way to overcome sin is "Walk in the Spirit and you will not fulfill the lusts of the Flesh". You cannot do it in your own strength.

If I can find some good testimonies I'll post them.

You can send me you email if you'd like.
