As a congregation we spent two Sundays on Mark 10:17-22 and then Mark 10:23-31 – the Rich Young Ruler and the aftermath explanations. [The LCMS three year lectionary cycle very closely follows the one used in most churches, but this is one of the places where it was modified. Instead of treating all that material in one week, and then reading the following request of James and John, we spend two weeks on the story itself and Jesus’ explanation.] The impression that is given at the end of the story is that the Rich Young Man did not follow Jesus – or that is the traditional take either being the example of seed falling among thorns (Mark 4:7) or just his walking away sad.
This link has a slight expansion using later parts of Mark to say that things might not have ended so sad for the rich young man. For some good counter arguments read the comment by Kim Fabricius in the chain.
Both are good close readings of the text.
