How do?

God is not stuck in time with us.  God can see all of human
activity.  God has given humans The Word to warn and to teach.
The Word by virtue of the Source of said word, has authority
of it's own, but never more that the source.  So when the Word
utters a warning the warning can't be "it will be" because it is a
warning that the folly won't happen.  It is called Love.
But because Love is worshiped, Love can not come out and say
it for the obvious reason that Love would MAKE it happen.
So it speaks in a rainbow.  When a folly is committed because the
warning was not heeded, then The Word is sounded definite.
But even then, because all do not share in the folly, the warning
can not be popularly understood.  That is called wisdom.  Because why
should the innocent suffer?  I'm an Earthling, I do not know about
that other stuff.

That is how.
