Since lust is related to our sexuality which is an intrinsic part of our human nature, I agree with the first post.
However, like any moral weakness, it can be tamed by a serious decision to conquer it through intensive prayer. We do need to depend on a higher power to overcome any weakness. But it is not just the concept of ending a bad personality trait, we should replace it with a higher trait, that of loving the Lord. For me, I use my love for Jesus and the desire to never disappoint him and to pleas my Creator.
Of course, I often fail, but over time, am becoming stronger. For me, I eat too much, and need to discipline myself. Although I do not consider myself a glutton, I am overweight and feel it is a sin for me to not able to get better control of my appetite. It is an eternal problem. It is inborn in all of us to have weaknesses.

It is more than that. It is desiring what you cannot have.
