1 Corinthians 10:13
[SIZE=2]13[/SIZE]No temptation has seized you except what is common to man. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can stand up under it.
Memorize this verse!!! You must memorize it, for you will need to bring it to bear instantly when temptaion arises. When the temptation arises, say the verse over and over and over and over (aloud or silent if in public), a 1000 times if need be. The desires wane and wax, you need only keep from falling prey to it for awhile. Eventually as you win more battles to resist it, you will gain cofindence in your ability to resist it, and it WILL become easier.
