How do we know the doctrine of the incarnation is true?

The truth of the incarnation is rooted in Scripture, particularly in John 1:14, which states that the Word became flesh. This claim is supported by the life and ministry of Jesus, who not only performed miracles but also fulfilled Old Testament prophecies regarding the Messiah. For example, Isaiah 7:14 prophesies that a virgin would conceive and bear a Son, which is a direct affirmation of God's presence among humanity. Additionally, the historical accounts of Jesus' life and death provide robust evidence of His identity as both God and man, affirming the reality of the incarnation as a foundational doctrine of the Christian faith.
