text: Right, yours is exactly the adjustment in understanding that Christians realized they had to make already by the end of the first century. But historians think the expectation of Jesus himself is well reflected in e.g. Mark 9.1, "Amen I tell you, there are some standing here who will not taste death until they see the Kingdom of God coming in power."
  
  Also note that the slightly different form of the saying in Matthew 16.28, perhaps based on an alternative edition of Mark, has another eschatological feature elsewhere used by Jesus: ". . . until they see the Son of Man coming in his kingdom." We think that although Jesus did think of himself as the Christ, which truth he tried to keep secret, he did NOT think he was the Son of Man, i.e. the heavenly figure of Daniel 7 (cf. Mark 14.62); but that identity was already recognized and affirmed by the end of the century, perhaps even by Mark. So the church comes to know all kinds of things that Jesus himself never knew! Big things too! (tbc)
