The good thing the man must do is show his fidelity toward God's covenant by obeying his laws. These laws were part of first-century Jewish culture, and the young man is convinced that he has kept them, as many of us have avoided breaking the laws of our society (compare Odeberg 1964:60). But if he is really ready to submit to the yoke of God's kingdom, he must also become a follower of Jesus and submit to Jesus' demands. That he is unwilling to spare all his goods to help the poor will soon bring into question whether he really loves his neighbor as himself (vv. 19-22).
