Luke's version of Mark 13 is to be found in Chapter 21. The three major prophetic sections of the discourse correspond to future persecutions of the disciples, the destruction of jerusalem, and the coming of the Son of Man. The first two, at the time of the writing of Luke, have already been fulfilled. The Book of Acts has narrated the persecution of the disciples, and Jerusalem was destroyed by the Romans in 70AD. The eschatological elements of the coming of the Son of Man in the third prophecy so general to be of no use to an apocalyptist. And the discourse ends with Luke's more full version of 'Keep awake'. (Mark 13:37; cf Luke 21:34-36)
All this is hardly surprising given apocalyptists' tendency to envision a future of salvation based on expunging all trace of sinners from God's future. There is no wholeness to be found at the expense of excluding others. Jesus' ministry, directed to the 'sick', and his death for the sins of the whole world as a victim of human sin and violence undercuts the point of apocalyptic's vision of purity.
