How do we know the incarnation of Christ is true?

The truth of Christ's incarnation is grounded in Scripture, particularly in John 1:14, which clearly affirms that the Word became flesh. Throughout the New Testament, we find consistent testimonies of Jesus' miraculous works, His teachings, His fulfillment of Old Testament prophecies, and His resurrection—all supporting the reality of His divine and human nature. The early church wrestled with this truth, ultimately codifying it in creeds and affirmations that highlight its essential nature for salvation. Without the incarnation, the redemptive work of Christ would be impossible.
