This was exactly what I was getting at . . . "commonly understood" by who? If you want I'll track down as many different interpretations and foil hat application for Daniel 9 as I can. Why is yours any better?
Christians spend to much time preoccupied with this stuff. Let me sum it up for you - good guys win, bad guys lose - do you need to know or understand anymore prohphecy than that?
Well, Christ himself thought that we should know at least SOME prophesy. He tells us to look for signs of the end. From Matthew chapter 33: "35 Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning: 36 Lest coming suddenly he find you sleeping. 37 And what I say unto you I say unto all, Watch."
I agree with you, we should not obsess on prophesy, as some do, but live our lives planning to live for years, but ready to go any minute.
