So when you say "Virgin is conceiving" it means, she is conceiving AT THAT VERY MOMENT when Isaiah wrote all these...
A very weak argument... First of all, how much English grammar and literature do you know? This is a basic English grammar issue you don't understand or don't want to understand to my surprise, for a person who had been supposedly living in the US for a long time. But English is not your native language so I am not suprised with that...
A: What is Michael going to do this summer?
B: He is running in the annual marathon...
Is Michael running at that present time (NOW as you say) as they were speaking about Michael... By your logic he is... There is not even a mention of the present time...
With this weak claim you proved that:
# Misunderstanding the historical context
# Misreading the text
# Not reading the entire text
# Having too literalistic an interpretation
Isn't that also interesting you pick the Bible with this verse supposedly making your point (out of 16 Bible versions all quoting this verse with future tense) ? This also proves:
# Imposing their own agenda...
