What role did Jesus promise the disciples in His future Kingdom?
Jesus promised that when He establishes His Kingdom and restores things as before the fall, the disciples will sit on twelve thrones beneath His, ruling the twelve tribes of Israel under Him as their King. They will occupy places of authority over Israel in that coming Kingdom.
Les explains that Jesus told the disciples that when He sets up His Kingdom, and everything is reverted back as it was before the fall, they are going to sit on twelve thrones figuratively beneath His, because He will be the King. They will be ruling the twelve tribes of Israel under Him. Their expectation of an earthly kingdom and places of authority over the twelve tribes was not refuted by Jesus; He only said the time was not for them to know. The fact that the Kingdom is coming, yes, but when it comes is known only by the Father.
