Luke 18:31-34 All Things Had To Be Accomplished.
This was still a point in his ministry when Jesus only wanted His disciples to know what was ahead. They would continue the journey to Jerusalem where at the proper time, “all things that are written by the prophets concerning the Son of Man will be accomplished” (v. 31). This eschatological title was a favourite of Jesus-it focused on His death, burial, resurrection, ascension, and enthronement at the right hand of the Father, and also the end of the old covenant era or ages. “All things” that the prophets wrote about, where about to be “accomplished,” not just some things. This would include the leadership of the old covenant nation delivering Him over to the Gentiles to mock, torture, and kill-to die an accursed death (vv. 32-33). However, it also would include Him rising on the third day.
Now one can imagine, given everything that has occurred up to this point, that anyone could readily accept that Jesus would indeed be betrayed by His own people and die in this way. But to rise from the dead-this would have been a stretch. However, we read that the disciples “understood none of these things” (v. 34). If His closest disciples, the twelve, did not understand, how much less the multitudes? But this is just Luke’s point-the truth of these things were hidden even from the twelve at this time. This would have to come out later, after fulfillment. This was not the first time Jesus made this prediction, in fact it was the third time He had made this prediction (Cf. 9:21-22; 43-45; Mt. 16:21-23; 17:22-23; 20:17-19; Mk. 8:31-33; 9:30-32; 10:32-34).
It is a common biblical principle that there are two or three witnesses, or a truth attested to two or three times that assures of a matter. And yet, this was still not understood after a threefold witness, because not only is the giving of revelation a sovereign condescending act on God’s part, but so is the understanding of it. On the second occasion of this prediction both Luke and Mark record that they were afraid to ask Jesus what He meant (9:45; Mk. 9:32), and Mathew records that they were sorrowful (Mt. 17:23). Was it because of His rebuke to Peter on the first occasion (Mt. 16:23; Mk. 8:33)? It escaped them that the anointed One would be anointed to the threefold office of prophet, priest, and king. He would reign in this threefold capacity. All things had to be accomplished.
