This still fails the test of the text itself. Most evangelicals take other references that are no more concrete or unambiguous than this as a definite reference to a Second Coming; in fact if you read the Hebrew usually translated "behold a virgin shall conceive" it's a tougher stretch than even that.
The problem is, that is how the Christian community itself at that time understood the verse, and other NT verses made LOTS of similar "any day now" kinds of end-timey eschatological predictions - to the point that over a few decades the NT writers were themselves forced to acknowledge the problem openly in their texts ("where is the promise of his coming?"), - and only THEN did they start devising alternative "interpretations" like, oh, well, "one day with the Lord is as a thousand years and a thousand years as one day."
Which is pretty much an acknowledgment of the failure itself and of course let the thing just keep stretching out for centuries, and centuries, and centuries, and centuries. That clearly fails any kind of test of falsifiability and therefore - ymmv, but just pointing out - especially given many other failed prophecies too - can not be reliably looked to as truth. Prediction was, any time now, any time now, any time now, in fact so soon people shouldn't even bother getting married, any time now - okay, we're going to "reinterpret."
Nope.
