This sin is the biggest thing that I have ever struggled with. But it is something I hope to overcome with the help of God's Grace. This is something that I want to stop now. Any advice and prayers for me would be greatly appreciated in this struggle.
Scripture says;
"If your eye causes you to sin - pluck it out."
"If your hand causes you to sin - cut it off".
"Make no provisions for the flesh".
"It is better to enter heaven deformed than to enter eternal fire whole".
This does not mean to literally pluck your eye out but to learn about your weaknesses, where your temptations come from and avoid those
near occasions of sin. This can mean averting your eyes from looking at something that will later be hard to not indulge your imagination about.
Dude, I am in my 40's and celibate but when a male enhancement or girls gone wild add comes on TV, I turn the channel because if I don't I will invariably start experiencing temptations. We are called to be a people of prayer.
If you have posters, inappropriate content or catalogs get rid of them. "Garbage in = garbage out".
If its your imagination thats most problematic then change your focus. Pray or find something to distract you. Cold showers etc etc and then pray, pray, pray some more.
Go to a prayer group and ask for prayers for deliverance from the spirit of fornication.
Above all persevere and don't give up. Forgive yourself if you fall and pick yourself up, dust off, get to confession and start again with a renewed resolve. Learn from the falls and try to do better next time if you find yourself in the same situation/temptation.
Something else that may help is realization that the woman who debases herself is harming herself as well as being an object of temptation for you. She is denying her God given dignity and being used and objectified because she probably doesn't like herself very much.
True love of women knows this and that type of undignified or promiscuous behavior should solicit feelings of pity or disgust from a Christan rather than lust and desire.
The secular world is geared to trick you into thinking debauchery is normal and acceptable. Jesus tells us to be in the world but not "OF" the world. This is a challenge for everyone.
