The apostles still had a poor idea of what the Kingdom that their Teacher brought into the world was, if they asked Him questions about who would occupy the places of honor beside Him in that Kingdom. For them, it was apparently a reality of our world, though an unusual one. Perhaps they thought the matter concerned an earthly state that, however, would be full of God's signs and wonders performed by their Teacher, who at last, with God's help, would take the place that belonged to Him. And the question about the cup and the washing, or "baptism," they most likely understood to mean that before the triumph all of them would face a long struggle, and each would receive no small share of suffering, which in general fit the messianic ideas accepted at the time.
Jesus, however, accepts their readiness, telling them that they will have to drink one cup with Him and be washed with one washing with Him, without going into details and without trying to explain anything to them. As can be seen, He understood that at that moment any explanations were useless: the disciples would not have understood Him anyway, just as they had not understood Him up to that point.
But Jesus tells His disciples right away that in His Kingdom everything is not as it is in earthly kingdoms, evidently so that they would have no illusions about this from the very beginning. As can be seen, He regards the inner readiness not to rule but to serve as the spiritual foundation without which there can be no question of life in the Kingdom. The details of the Kingdom's structure, however, He evidently considers less important: if the disciples do not understand them now, they will understand later, having acquired the corresponding spiritual experience. Thus the Savior Himself sets the priorities where spiritual life is concerned: first comes what is necessary in order to enter the Kingdom, and only afterward, as spiritual experience is accumulated, everything else.
