How do we know the doctrine of Jesus Christ's incarnation is true?

The doctrine of the incarnation—that God became flesh in the person of Jesus Christ—is central to Christian faith and is affirmed through both direct scriptural testimony and prophetic fulfillment. The Apostle John emphasizes the necessity of recognizing Jesus Christ as having come in the flesh; to deny this is to welcome the spirit of Antichrist. This is supported by multiple affirmations in Scripture, including the declarations of Christ’s birth and His ministry, which align with Old Testament prophecies about the Messiah.

Additionally, the apostolic teachings consistently reaffirm Jesus’ true humanity coupled with His divinity. The New Testament writings provide a plethora of teachings regarding His life, death, and resurrection, asserting that He accomplished the redemption of His people. Recognizing the significance of the incarnation, believers capitalize on not only the historical realities but also the transformative power of the gospel, which speaks to the assurance of the truth of this doctrine.
