Matthew 5:29 (NLT)
So if your eye—even your good eye—causes you to lust, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell.
"…there is a mean streak to authentic self-control…Self-control is not for the timid. When we want to grow in it, not only do we nurture an exuberance for Jesus Christ, we also demand of ourselves a hatred for sin…The only possible attitude toward out-of-control desire is a declaration of all-out war…There is something about war that sharpens the senses…War keeps us vigilant.”
- Ed Welch (Self Control: The Battle Against 'One More')
