Ignore my anachronistic failing of using Kool-Aid millennia before its invention...
I assume the "grape juice" thingie is a slap at me on the assumption that I am a Fundamentalist Protestant. I'm sorry to disappoint you.
Let me put it to you this way. You have no way whatsoever to prove the "virgin birth" or any other "miracle" of the "new testament" but you accept them all nevertheless out of fideism. Anyone who does this--and who has an "old testement" in his bible--can likewise fideistically accept the totally extra-natural, pre-natural ceation and formation of the universe before it began to function in accordance with "natural law" on the sixth day.
Let me put it another way. If you can't prove the virgin birth but choose to believe it and feel the need to put down people who can't prove Sheshet Yemei Bre'shit but believe it, then you are a living, breathing definition of hypocrisy.
But as a Jew you do read Isaiah ???
Therefore the Lord himself will give you a sign: A virgin will be with child and will give birth to a son, and will call him Immanuel. Isaiah 7:14
Where's the hypocrisy is not believing what can be disproved, but having faith in what hasn't been disproved???
Is it possible the Lord made a universe where He put a bunch of stuff to fake us into thinking it's older than 6,000? Of course He can do that. I just choose not to worship a God who would be that much of a doofus.
