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

The birth of Christ is of utmost significance in Christian theology as it marks the greatest event between the eternities, demonstrating God's plan to redeem humanity. God chose the time, place, and means of Christ's entrance into the world to fulfill prophecies, such as being born in Bethlehem as foretold in Micah 5:2. This event signifies the moment God was manifest in flesh (1 Timothy 3:16), thus initiating the fulfillment of the covenant and bringing salvation to His people. The angels heralded this event declaring it as 'good tidings of great joy' for all people (Luke 2:10), illustrating its importance for humanity's hope and redemption.
