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

The visitation of Christ is a central doctrine evidenced by the fulfillment of Old Testament prophecies that pointed to His coming. Luke 1:68-69 speaks of God raising up a 'horn of salvation' from the house of David, reflecting God's faithfulness to His covenant promises. The experiences of figures like Zacharias, who proclaimed that God 'hath visited and redeemed His people,' further affirm the truth of this doctrine. The historical accounts and eyewitness testimonies within the Gospels provide a rich foundation for the belief that Jesus' coming fulfills God's redemptive plan laid out since the beginning of time.
