Does Mark 9:1 set a false date for the second coming?

Here are some comments I posted in the YouTube thread on early Christian eschatology that I linked earlier:

Some Problems With Singling Out Mark 13:30

Critics of early Christian eschatology often allege that Mark 13:30 makes a false prediction that Jesus' second coming will occur before the end of his generation. There are multiple contextual problems with that interpretation, as I've discussed on other occasions (verse 29 excludes the second coming from the "all these things" of verse 30, and verses 32-33 deny that a date can be set for the second coming). But what if a critic would suggest that we remove verse 30 from its surrounding context and take it as a genuine record of what the historical Jesus taught, whereas the surrounding context I've referred to is inauthentic?

Was Jesus a false prophet?

Here's a really good video by Than Christopoulos and Bram Rawlings on the claim that Jesus and the early Christians falsely predicted the timing of the second coming. This is a topic that critics of Christianity often bring up, but Christians typically don't respond nearly as well as they could. Bram makes many significant points, and I recommend keeping a record of the URL for future reference. (He also writes for Think Christian Theism, and you can find some posts there on these eschatological issues.)
