A man asked Jesus what he must do to gain eternal life. This reflects the typical religious attitude Jesus had been teaching against. The man ended up walking away saddened, because he wanted to earn righteous standing instead of simply asking for mercy from Jesus. Jesus' conversation with the man highlights the deceitfulness of the human heart and exposes what the man truly wanted, which wasn't forgiveness. Often, people are deceived into thinking they can do enough to be good with God, but in reality all people need to simply ask for God to have mercy on them through Jesus.
