>>Luke 1:31,34 - the angel tells Mary that you “will” conceive (using the future tense). Mary responds by saying, “How shall this be?” Mary’s response demonstrates that she had taken a vow of lifelong virginity by having no intention to have relations with a man.<<
Are you serious? You quote only half of verse 34 to make your point? This is very disingenuous since you fill in your own reason even though the other half of the verse clarifies the question thus:
Verse 34: “How will this be,” Mary asked the angel, “since I am a virgin?”
Your question is answered right there. And please note the word “am”, not “will always be”. And your omission of this information causes me to question your sincerity in getting to the honest truth here.
Really? What about that little detail of Mary being bethothed to Joseph? (Matt. 1:18; Luke 1:27)
