Ten years ago I know that I know that I know that I was truly born again, but the last few years it seems i've been caught in this cycle.
My biggest problem is lust. It seems I fail God and sin in this area and then I thouroughly repent and God forgives me and I feel free and clean and dead to sin - and this usually last for a few weeks or a month maybe even two, but then it's like I wake up one day and my flesh feels so alive. I don't know if it's hormones or what - I'm a 21 year old male - but it's like these lustful urgers are there - and I try to fight them off as long as I can but eventually i give in to them. and fail again and sin again - then i'm usually stuck in this pit for a few days - then I repent and the the process starts all over again.
Is this normal Chrisitianity? What am I to do? I want my old man to die and stay dead forever and to never be resurrected again.
Everyone struggles with lust, men and women. Older saints often tell me it gets better with time. I'm a single pentecostal and gave up worldly dating after being baptized with the holy spirit and I was celibate long before that. I know how you feel.
The important part is to never give up, the lord will give you deliverance, you just have to hold onto that promise. Keep praying, it also helps to fast as well (either the daniel fast or just skipping breakfast is fine).
Don't dwell on self condemnation, our savior is a merciful , and patient too. Ask god to give you the desire not to indulge in your flesh, always ask the lord for help.
If you want victory then start by making a covenant with your eyes, promise the lord you will not look at images which incite lust. This doesn't only mean porn, sometimes looking at t.v which show partial nudity can get those thoughts going, so be careful what you watch. You may live or work in an environment where you encounter immodest women, make the best of it and try to look away. Take it one step at a time, sometimes trying to quit cold turkey can be too much, so start by not looking at any inappropriate images. Those images may dwell in your mind, but if you don't indulge your eyes then those images will fade with time. If you have looked at pornography in the past and images keep playing in you mind when your not viewing it, ask god to erase those memories.
You may come across women who try to entice you, the enemy is using them as a means for your downfall, don't give in. Ask the lord to bind up the works of the enemy(in Jesus name). If you keep fighting you will see victory. And you must because you won't be ready for a godly marriage if you have not mastered self control( I'm assuming you're single maybe I'm wrong) Doesn't matter how many times you have to tell the devil no, keep saying no.
In the meantime, ask the lord to show you that special woman who will be your future wife.
Hope this helps.
