I think that we can speculate that this might be considered a person's most valuable asset. His name! That is, the name of God that we now bear, and of which the commandment says, You shall not bear that name in vain. Now what are you doing to uphold the Family name? Are you guiltless? Are you clean in your bearing of it? What is your witness like before men? What is your witness like before God? These questions need to be asked - now that we know that we bear that name. What is the quality of your Christian life?
Remember that word vanity? What does it mean? It means falsehood. It means lies - that which is lacking in reality, in truth.
