Lust is a distortion of passionate desire. Pride is a distortion of self-esteem. There is nothing wrong with bodily desires until they become distorted or fragmented off from their proper relationship with other aspects of you. Now we'll use sex as our illustration here for a minute. Sex is good.
Sexual desire is good.
Sexual intimacy is good. They must be, God made them and God said they were good. But if they get distorted or fragmented off from the place they are designed to occupy in your life then they won't function healthily, they mutate and become like cancers that start corrupting other parts of your life. Sexual desire is good, sacred even, and like anything sacred, handle it wrongly and its sacred power becomes destructive instead of life-giving. Just think about your own experience of the expression of sexual desire, even at simple preliminary levels with your clothes on.
