How do we know the virgin birth of Christ is true?

The truth of the virgin birth of Christ is established in the Bible, particularly in accounts found in Matthew 1 and Luke 1. These passages reveal that Mary conceived by the Holy Spirit, ensuring that Jesus was not born of sinful human nature. Additionally, this miraculous event fulfills the prophecy in Isaiah 7:14, which proves God's sovereignty and plan for redemption through His Son. Denying the virgin birth undermines the essential doctrines of Christianity, including Christ's deity and sinless humanity, which are vital for our understanding of His role as the Savior. The virgin birth signifies that Christ is capable of saving His people from their sins, as it is the righteousness of God that secures our salvation.
