Would seeking the other person's highest good in dating prevent moral shambles?
Yes. When dating is governed by a love that seeks the other person's highest good, moral shambles are avoided. Paul defines true love this way, and such love does not seek to bring another into immorality; it fulfills the law.
Les explains that the love Paul speaks of is not erotic love or Hollywood's idea of love, but a love that seeks the other person's highest good. If young people in their courting and dating kept that uppermost in mind, they would not be in the moral shambles we see today. If a young man dating a girl had her highest good on his mind, he would not try to bring her into an immoral state. The same applies to a husband and wife or a neighbor with a neighbor: as long as we do whatever we do for the other person's highest good, Paul says we are fulfilling the whole law. Yet this cannot be done merely on the basis of commanding, because we never really grow up.
