The 'myth' states that the world would be blessed through Abraham's seed. This was fulfilled in the death and resurrection of Christ. God's glory was in the Temple until the Exile, when it left and didn't return until Jesus came. Jesus then left it desolate (Matthew 23) and so it is no longer a sacred site and belongs to whoever can hold it.
Not much of a prophecy, was it!
According to the Old Goat Herder's Book of Myths and Fairy Tales, there were 42 generations between Abraham and Jesus.
A quick calculation suggests that if each individual in each generation had just two children, by the time of Jesus, Abraham's seed would have accounted for than 400,000,000,0000 individuals. Just about anyone on Planet Earth alive at that time would have been qualified to fulfil the prophecy. Most, I suspect, several times over.
And for that THAT we have the international instability that now afflicts us?
