Dave gives his members encouragement that there will be lots of "public servants" in the kingdom to help them...angels. Since angels are highly intelligent and have opinions, it is up to the RCG members to decide if they want to listen to them or reject their opinions.
One encouraging thing is you have a huge number of public servants, who are angels…but hey, you’re judging them, they’re not judging you. That doesn’t mean they couldn’t have an opinion, if God has built into their minds the ability to offer one, and they can certainly carry out things. You don’t have to carry them out. So you’re not standing alone, and maybe it depends on how much character you brought to the table. Because, remember, skills and experience are not transferable. Character—to God—holy, righteous, perfect character—including how much you serve—is absolutely transferable. That is the one thing He cannot give you…but knowledge of how to do everything that you need to do, you cannot possibly bring to Him…or wisdom or these other gifts.
