Old jeans with new patches. Old wineskins with new wine. These are some analogies that Jesus puts forth to show us the incompatibility of his ways and the old ways. This has a million applications to us today, but first we need to understand how the old is embodied in the new.
Jesus speaks identity into his disciples. He changes Simon's name to Peter. He nicknames the other Simon "the Zealot." He nicknames two others "The Sons of Thunder." He calls 12 of them "apostles." Jesus invests calling in them through names, and titles. What names and titles is he speaking over you? What names and titles does he want you to speak over others?
