Calvinist perspective on Luke 18:18-30

[Luke 18:18-30 (NIV)](http://www.biblegateway.com/passage/?search=Luke%2018:18-30&version=NIV) tells the story of the "rich young ruler" who asked Christ what he must do to inherit eternal life: > 18A certain ruler asked him, “Good teacher, what must I do to inherit eternal life?” ... > > 22 ...[Jesus] said to him, “You still lack one thing. Sell everything you have and give to the poor, and you will have treasure in heaven. Then come, follow me.” My understanding of Calvinism is that salvation (from the Calvinist perspective) is entirely a work of God, and no human can do anything, even including "accepting" the gift of salvation, to affect their salvation. These instructions from Jesus appear to contradict this concept. Jesus seems to be offering to the ruler some concrete actions he could take to ensure his salvation. Granted, based on the ruler's reaction, his heart was in the wrong place, as he was unwilling to do what Christ commanded. So really, Christ's commandment was not about the act of giving away possessions, but about the state of the man's heart. But if the truth is that the man was powerless to affect his salvation, wasn't Christ in effect lying by suggesting the ruler _could_ do these actions (and change his heart) in order to achieve eternal life? What is the Calvinist interpretation of this (and other similar) stories?
