Love vs Lust

Elder Jeffrey R. Holland gave a great description of the some of the differences between love and lust in a conference talk he gave.

Why is lust such a deadly sin? Well, in addition to the completely spirit-destroying impact it has upon our souls, I think it is a sin because it defiles the highest and holiest relationship God has given us in mortality, the love that a man and a woman have for each other and the desire that couple has to bring children into a family intended to be forever. Someone once said that true love must include the idea of permanence. True love endures, but lust changes as quickly as it can turn a pornographic page or glance at yet another potential object for gratification walking by, male or female.

True love we are absolutely giddy about as I am about Sister Holland. We shout it from the housetops, but lust is characterized by shame, stealth and is almost pathologically clandestine.
