I'm not sure where the reference is exactly, but Jesus Himself said that if a man looks at a woman in an impure way he has already committed adultery with her. That particular verse really gives me the ebee-geebees, but I really think that this, like everything else about our walk with the Lord, is a matter of heart. I really don't think that if a man sees a beautiful woman and finds himself attracted to her for a second, but realizes what's going on, diverts his eyes and repents that he has committed adultery. I believe that happeneds when that same man dwells on the image and fills his heart and mind with thoughts of what would be like to be with her and finds himself no longer being attracted to his own wife and wishing she would either be that other woman or at least look like her. I really think there is a fine line we all must walk and the biggest, most wonderful thing that God has given us to help us in our walk is the power and privilege of repentance! My opinion!
