Another questionable line of interpretation, if I may make so bold….
Jesus says to his disciples, “I will give you a mouth and a wisdom that none of those who oppose you will be able to stand against or contradict” (Lk. 21:14-15). Since his imminent death is in view, he must mean that he will have authority “to confer speech and wisdom in a supernatural manner” beyond death, in Richard Hays’ words. We may compare God’s promise to Moses: “Now go, I will be with your mouth and teach you what you are to speak” (Exod. 4:11-12).
In Reading Backwards: Figural Christology and the Fourfold Gospel Witness Hays asks how it is that Jesus has such authority (71). How is it that he can confer powers and blessing “that no one but God could confer”? How can he appoint disciples and give them authority over demons and diseases? How can he promise to send power from on high upon his followers and then “in the dramatic opening scenes of Acts, fulfil that promise by pouring out the Holy Spirit”? Surely the power to send the Spirit “is a prerogative that belongs exclusively to God”?
