2 Tim. 2:15 is your friend.
But 1 Cor. 6:2 states we, which must include Paul, shall judge angels, thus establishing judgment is not left to simply the 12, while Matt. 19:27-30 says "ye which have followed me," forsaking all, shall also sit upon twelve thrones, and it is clear more than one person can occupy a throne, which represents judgment as regards the 12.
However, i do see this as most likely referring to 12 thrones for the 12 foundational apostles, but nothing more is said of this except that "I saw thrones, and they sat upon them, and judgment was given unto them." (Revelation 20:4)
And this is for the final judgment, just as believers will judge angels, though in the millennium all the elect shall be priests of God and of Christ, and shall reign with him a thousand years. (Revelation 20:6)
This can be seen as inferring the apostles will sit in rule over Israel in the millennium reign of Christ (and which reality is one of the many things we concur on), but once again you are resorting making what can be inferred into something definite, including that Paul cannot be one of the judges, in order to make Peter and co. preach a different gospel than Paul's, but which is simply not what the totality of the NT reveals. And the former premise (which i can allow) does not equate to the latter conclusion.
Now may you have another God night! Now
"Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?" (1 John 5:5)
Being secure in Christ IS overcoming.
Great discussion FRiends.May His Spirit reign in it!
