Below are two interesting articles by Al Mohler on the virgin birth. Both are excellent for deepening your understanding of the doctrine and having some tools to defend it.
This last article is from a magazine in the UK that interviewed church leaders about the importance of the virgin birth. It’s a sad reminder of what happens when you abandon the Bible in favor of tradition, or even worse, sentimentality. I think the most disturbing response in the whole piece came from James Delingpole, “Me, I care more about hymns having the right tunes, and the Prayer Book being 1662.”
