After His mother Mary was betrothed to Joseph, before they came together, she was found with child of the Holy Spirit.
The virgin birth is an underlying assumption in everything the Bible says about Jesus. To throw out the virgin birth is to reject Christ’s deity, the accuracy and authority of Scripture, and a host of other related doctrines that are the heart of the Christian faith. No issue is more important than the virgin birth to our understanding of who Jesus is. If we deny that Jesus is God, we have denied the very essence of Christianity. Everything else the Bible teaches about Christ hinges on the truth we celebrate at Christmas—that Jesus is God in human flesh. If the story of His birth is merely a fabricated or trumped–up legend, then so is the rest of what Scripture tells us about Him. The virgin birth is as crucial as the resurrection in substantiating His deity. It is not an optional truth. Anyone who rejects Christ’s deity rejects Christ absolutely—even if he pretends otherwise (see 1 John 4:1–3).
