Somehow this is a tricky question because no matter what you say christians could use it against you. If you say that you fight sin and try to resist sin then somebody might say: Wait a minute! You are trying to fight against sin in your own strength, this will never work... But what's the alternative? Just waiting for the Lord to miraculously free us from all kinds of temptations? No, this isn't an alternative. I think we have to fight sin and be determined. After all Paul says this: Heb 12:4 Ye have not yet resisted unto blood, striving against sin. I am sick of sinning and then whining about it afterwards. I want to change this. How can I respect myself when I behave like a whimp and sin only to whine about it later on? I want to be able to look in the mirror and say that I really did my best to resist sin. And I think that you can really get satisfaction from resisting sin because if you win then you'll feel good about it, right?
