I have never really managed to get to grips with the 'Timeline'.
Just what is supposed to happen when I click on this flag?

For me it opens up with the year 2000 on the far right of the window and I can find no mention of the Financial Collapse referred to.
This particular flag can be found in Goldingay 'Job for Everyone' expounding on Chapter 15.
(Actually after moving from Wright's 'Christian Origins Series' I should really be grateful to find a flag at all.)
