Enemy has been attacking me extremely bad in my body and putting evil thoughts continually in my mind.
The next time your tempted, praise the Lord with all that you have in you. I have found that when I am being tempted I say the name of Jesus outloud and in my mind and the temptation goes away speedily.
The next time you have a dirty thought, cast it down. Yes, cast it down, imagine in your mind stamping on it. But it takes some effort on your part, it takes your cooperation.
What do you want the most, the pleasure in sin for a season or being free?
Every man will say "being free" of course, but when the temptation comes the story changes. We want what the temptation is offering because it appeals to the lust that is already in our members.
Did you know that every man has a lust of some kind? And there are times that we are enticed and drawn away with it. It's there and will probably remain there to our dying day. However, it doesn't mean that we let it control us.
The sooner you get that settled in your heart the better it will be for you; that failure is a part of growing.
So you fell, well get back up. It doesn't matter how many times you fall down, keep crying out to the Lord for help and get up again, it's the crying out to God for help that makes all the difference in your journey through faith. Even when you enjoyed what you fell into, keep going back to the Lord for help.
When you started this thread you were in the realm of fretting. You were engulfed in the fear of falling into sin again and it was overwhelming you. Again, settle it in your heart that your going to fall. The sooner you accept that the better because that fear will constantly come upon you and the enemy will use it against you.
Don't wallow in your self pity or say "oh woe is me", get up from sinning and say, "Father I sinned again, cleanse me from all unrighteousness."
Don't fail to turn your sins over to Him because remember Christ is our sin bearer, He took the sins of the world upon Himself and He became sin for us. If you hold unto sin, your holding unto something that is rightfully His. So give it to Him because He alone knows how to forgive you. Fob it onto Him as soon as you can, if you don't death starts to spread and your heart will become hardened and you don't want that to happen.
Remember, it doesn't matter how many times you sin, get right back up again asking Him to forgive you. In the beginning of our journey with God, there are some of us that seem to live a "sin repent, sin repent" walk. But remember when you continue to call upon the Lord for help, that status will change over time as you learn to grow in grace and in the knowledge of Him.
