Matthew 16:21-23 His Reign Must Follow His Death And Resurrection.
Matthew records that “from that time Jesus began to show to His disciples that He must go to Jerusalem” (v. 21a). One does not imagine that Jesus showed them on a map, as it were, nor that he gave some kind of visual display of what was about to take place there. Clearly he was showing them from the scriptures that the upcoming events had to take place. This also explains why he earlier wanted them to remain quiet about who he was, because they clearly did not understand what had to take place before he began to reign as the Messiah, and Son of the living God, that they through Peter had declared him to be (Cf. vv. 13-20; Lk. 9:18-22). This understanding of what he was now showing them is borne out by later record (Cf. Lk. 18:31-33; 24:46).
In Luke’s record the emphasis is on the actions of the Gentiles, but here in Matthew it is that of the apostate Jewish leadership. Clearly both parties were guilty, but each writer had their own particular purpose and emphasis. However, together they, along with the other New Testament writers, bear witness to him being killed and rising on the third day (v. 21b). Peter, the one who bore true testimony to who Jesus was, by the sovereign revelation of the Father, was equally adamant that he should not allow this death to take place. However, now Peter’s words were inspired by Satan and not the Father (vv. 22-23a). At this point Peter was only mindful of the things of men, and not of God, a reign that would bypass the cross and the resurrection (v. 23b).
