What does the Bible say about the importance of Christ's coming?

Christ’s coming is essential for salvation, as it fulfilled the prophecies and purposes of God, demonstrating His love and mercy. Had He not been born, there would be no opportunity for redemption. Additionally, His sinless life, marked by His divine nature and the virgin birth, distinguishes Him from humanity, enabling Him to save us as our perfect Savior. This event is celebrated and remembered because it set into motion the work needed for our justification and reconciliation with God.
