Jesus's birth marks the division of time into B.C. and A.D., signifying his immense impact.
The designation of time as B.C. (Before Christ) and A.D. (Anno Domini, Latin for 'in the year of our Lord') demonstrates Jesus's pivotal role in history. Every person, regardless of belief, recognizes the significance of Christ’s birth as a turning point in human history. This division signifies the profound theological assertion that Jesus is the focal point of God's creation and redemption plan. As noted in Matthew 1:21, 'You shall call his name Jesus, for he will save his people from their sins,' asserting that his incarnation changed the course of history. The impact of Christ extends beyond mere chronology; it delineates the transition from the old covenant to the new covenant of grace.
