Dispensational Doctrine and the 70 Weeks Prophecy

The text seems to be directed to the children of Israel according to the flesh so it is understandable that some would believe the promises applied to them. Paul hastens to correct this saying; the seed does not mean many descendents but only one which is Christ. They who may qualify to receive blessing has changed from a natural birthright to that which is spiritual by being born again. The new covenant in Christ has made the first one old and ready to vanish away.
