What is love without lust? Lust defined as sexual desire. If you have a male/female relationship there should be some lust to begin with or else the relationship is dry and colorless; based on some other motive like money or reputation. Christians often substitute the word lust for attraction, but they really mean the same thing that atheists mean when they say lust. Attraction lust and desire should be brought on by perceived beauty in the other person whether physical, intellectual, spiritual or otherwise. There could be an argument that says that lust is a more extreme and unhealthy form of attraction based on an obsession or perverted preoccupation, but what's perverted about having sexual feelings for someone of the opposite sex? And unsaved people don't define lust as something obsessive. Perhaps Jesus meant something different when he said lusting in the heart was a sin of adultery. Because if it means sexual attraction surely one can't help that any more than they can help having an opinion about what colors they like, or what foods they like. And surely lust is acceptable in a marriage relationship.
