I think the current Governing Body will eventually be forced to send out "feelers" to see who might be interested in joining the body... The feeler will likely have this "invitation" at the end...
Brother DO... lately, we have noticed the holy spirit advancing kingdom interests like never before. It has been directing our decision-making with clear direction on which of Jehovah's servants are most qualified to shepherd the flock in the few remaining days of this system. You will do well in giving prayerful consideration into whether or not you may be in line for the heavenly calling. To this end, we would like to meet with you on XXXXXXXX to discuss your theocratic goals and also to determine your possible status as one of Jehovah's annointed."
