Why does Love triumph over the Law in the New Testament?

Love is more important than Law in the New Testament because Love encompasses all things. If we truly loved God with all of our being we would never sin. Sin is always a result of loving something more than God, whether that be an action, a person or ourselves. This is why loving God is the greatest commandment and loving others is the second greatest commandment. We do not need law if we follow these two commandments.
