I really don't agree with the timelines, because these are based on dispensational theology which has more holes in it than the proverbial Swiss cheese. I like the clarity that things like this provide, but I recommend that people double-check the actual content. Anybody can make a chart; that doesn't make the chart accurate.

I think they great for study.. but I still find the Doc Gosey

C.C. Gosey Bible Charts, Maps and Free Bible Charts

Charts a lot easier to understand... I've used them for home studys for years.
