OK.
Out of curiosity, do you think they quoted Jesus of Nazareth correctly? Do you think they quoted Him at all? Do you think they fabricated the quote? Do you think they fabricated Jesus of Nazareth?
BTW, while there's nothing amiss with "It's wrong because God said so", there is another angle from which to consider the problematic nature of lust. Lust treats its object as a mere thing, to be used for one's personal gratification. It is a perversion of Love, which treats its object as a person to be cherished and built up, and to be a partner in a mutually beneficial relationship. FWIW. If you think it's OK to treat people as things, that's your choice. Others might find it interesting or valuable to know that you harbor that attitude, though.
I think that would be impossible for me to really know. I believe Jesus the man lived.
While that is the popular belief, I really don’t know if lust actually treats it’s object as a mere thing, or if there is something more to it. Perhaps that is what lust was designed for, and it’s not really a perversion of love but something completely seperate from it.
