[Pass-by]

So my former Christian fren told me is correct. I got one question forget to add. How can a virgin be pregnant as in Mary case? He told me that is a miracle so possibly in those times test tube babies tech is available and God is most likely male since he impregnated Mary but why virgin is becuz Jesus is supposed to wash away human sin and Mary is human so it cannot be done the normal creation process else Jesus blood is tainted cannot wash our sins away

Maybe you should not use the term "he impregnated Mary" becus Mary is virgin?
