A challenge for LDS apologists who celebrate living apostles as the necessary and authoritative interpreters of scripture:
When making your case for something, limit your appeal to scripture and to the writings and speeches of LDS apostles, with attention to the historic development of LDS apostolic interpretation.
In other words, show that your appeal to the living apostles isn’t an honorable mention, head-fake, or vaporware. Make actual use of them — quote them — in your handling of scripture. Show that you actually, unembarrassingly prefer them over non-authoritative sources.
