Jesus balanced the need for humility and service with a promise of future reward. Though the Twelve are in view the implication of reward for other faithful disciples is strong. Jesus evidently repeated this promise in different language from an earlier situation (Matt. 19:28).
22:28 The basis of the reward is essentially faithfulness to Jesus (cf. Matt. 19:28). This is always the basis for believers' rewards, works being the consequence of faithfulness. Here the manifestation of faithfulness was standing by Jesus in His past trials (Gr. pairasmos, i.e., dangers, troubles; cf. Acts 20:19). Satan was behind these difficulties.
22:29-30 The Father had delegated authority to the Son to rule in the kingdom. Likewise the Son delegated authority to the Twelve to rule under Him in the kingdom (cf. John 20:21; 2 Tim. 2:12; Rev. 2:26-27; 3:21). They would enjoy table fellowship with Jesus then as well as the privilege of having authority over the twelve tribes of Israel then (cf. Dan. 7:9; Rev. 7:1-8). This is another reference to the messianic banquet (cf. 13:28-30; 14:15; 22:16).
"Luke, by the way he has structured his two-volume work and by the insertion of material peculiar to him, displays an unmistakable interest in the question of the national restoration of Israel. . . .
"Luke's manner of representing the nationalistic hopes of the Jewish people implies that he himself believed that there would be a future, national restoration. If Luke really believed that there would not be a restoration, he has certainly gone out of his way to give the contrary impression."478
Jesus spoke of twelve disciples even though Judas would disqualify himself. This was gracious of Jesus and implied that there was still time for Judas to repent. Evidently since he did not repent Matthias will take his place in the kingdom (Acts 1:26). It is interesting that the choice of Matthias took place in an upper room, perhaps the same one as this one (Acts 1:13).
Upcoming events would test the faithfulness of the Eleven soon (cf. vv. 31-34). This promise doubtless encouraged them to stand by Jesus in His future trials, though they failed Him. The theme of testing and faithfulness is quite prominent in Luke.479
