The virgin birth was necessary to ensure that Christ was sinless and fulfilled the Scriptures, making Him the perfect sacrifice for our sins.
The necessity of the virgin birth lies in the need for Christ to be free from original sin, which is passed down through human lineage. As stated in 1 Corinthians 15:22, in Adam all die, meaning that everyone born of Adam is born with a sinful nature. If Christ were born through natural means, He would inherit this sinful nature and thus be incapable of being an acceptable sacrifice for our sins. The virgin birth, therefore, is crucial as it fulfills prophetic Scripture and guarantees that Christ is the holy, harmless, spotless Lamb of God. He must be without sin to bear the sins of His people, as stated in 2 Corinthians 5:21, where it says He who knew no sin became sin for us, that we might become the righteousness of God in Him.
