Means that nothing can stop what's coming, regardless of which way that goes, it is up to US to decide together on how we want are World to reach its final destination.
Had an interesting dream years ago, where the father of the bride(interpreted as GOD), wouldn't tell his daughter about her future husbands darkness.
When it was finally discovered that the groom was not a good man and GOD was approached on why he did not spill the beans, his response was,
"Had I told you, You would not have believed me and our relationship would have broken, you had to learn on your own the Truth of who he was."
Took that as a long road for us to Discover the truth of the world. The finish line is always so much more rewarding when we actually run the race and are not driven to the end point.
