I believe you are misinterpreting 1 Corinthians 15:24. You are interpreting it as if it's talking about literally all rule, authority and power being put down, but that isn't what it is talking about. That is talking about Jesus putting down (destroying) all of the rule, authority and power of His enemies. It doesn't say that even Jesus or the disciples won't have any rule or power at that point. Of course He will and of course they will for eternity.
Surely, you understand that someone can be in power, but still have to answer to someone above them? That will be the case at that point. Jesus will still have authority and power, but will be subject unto the Father. Similarly, believers that are referenced in Jesus's parable will have authority, but will be subject to Jesus and to the Father.
Eric, it's entirely possible that I have somewhat been misunderstanding 1 Corinthians 15:24 since what you submitted makes good sense to me and that I have no problem admitting that. But even if you are correct about that verse and that I'm not, there are still some other things to factor in.
1 Corinthians 15:24 Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power.
The question is, pertaining to the parable I submitted from Luke 19, this authority that Jesus rewards His faithful servants with when He returns, should we assume, regardless what this authority might actually look like, that He is giving it to them forever, thus they utilize this authority throughout all eternity, or should we assume He is giving them this authority until 1 Corinthians 15:24 is fulfilled?
No matter how you look at it, He gives them this authority before the GWTJ is past, based on the fact what Luke 19:27 records.
Luke 19:27 But those mine enemies, which would not that I should reign over them, bring hither, and slay them before me.
Obviously, and even you couldn't possibly disagree, regardless what verse 27 actually looks like when it is being fulfilled, it is meaning before or maybe even during the GWTJ, certainly not after that judgment. This at least tells us, regardless that this a parable, as of verse 27, the end meant in 1 Corinthians 15:24 has not arrived yet since it would be ludicrous to apply Luke 19:27 after 1 Corinthians 15:24 has been fulfilled rather than before it has been fulfilled.
If one argues, that since this is a parable this means none of this actually involves literal events, such as Christ giving anyone authority when He returns, regardless what that might actually look like, is that same one also going to argue, where someone, Christ in this case, actually literally leaves the planet, goes somewhere else for awhile, heaven in this case, then returns to the earth some centuries later, that that doesn't actually involve literal events, either?
After all, it makes zero sense to take the latter to involve literal events, but these other things, such as rewarding faithful servants with authority over things when He returns, that none of that should be taken in a literal sense where He actually does something like that when He returns. Sounds like cherry picking to me.
