was it all a mishmash.
It is all a mishmash. Here's a quote from one of Bart Ehrman's books:
The Delay of the End of Time.
Luke’s idea of the divine plan relates to one other distinctive aspect of his Gospel. In Mark and Matthew, as we saw, Jesus predicts the imminent end of the world. In Luke all of these predictions about the end are worded differently. In Luke, Jesus does not envisage the end of the age happening immediately. How could he? First the Christian church had to be spread among the Gentiles, and this would take time.
Consider the differences between the apocalyptic predictions of Mark and those of Luke. In Mark 9:1, Jesus claims that some of his disciples will not taste death “until they see that the kingdom of God has come with power.” Luke has the same story, but here the disciples are told simply that some of them will not taste death until “they see the kingdom of God” (9:27; note that they are not promised to see its “coming in power,” i.e., with the coming of the Son of Man). For Luke, the disciples already see the kingdom of God, because for him the kingdom of God is already present in Jesus’ ministry. This becomes clear in several stories found only in Luke: the kingdom of God is said to have “come near” in the ministry of Jesus’ disciples (14:9, 11), it is said to have already “come to you” in Jesus’ own ministry (11:20), and it is said already to be “among you” in the person of Jesus himself (17:21). To be sure, even in Luke there is to be a final cataclysmic end to history at the end of this age (21:7-32), but this will not come during the disciples’ lifetime.
Luke’s emphasis on the delay of the end also explains the difference in Jesus’ reply when interrogated by the high priest. Whereas in Mark Jesus stated that the high priest would “see the Son of Man seated at the right hand of the Power, and coming with the clouds of heaven” (14:62), in Luke his response is simply that “from now on the Son of Man will be seated at the right hand of the power of God” (22:69). Luke appears to know full well that this high priest would not live to see the Son of Man coming in his glory to bring the end of the age; in his version of the story, Jesus never predicts that he will.
So there you are- the Gospels don't agree with each other, and as the Bible was written over a period of time the writers have updated Jesus' words to remain relevant. All of the New Testament was written for a 1st century audience- there is nothing there for us. Sorry.
