Question: In what year was Jesus born?
Answer: It is good that we want to know about Jesus. One can never learn too much about the greatest man to have ever walked on earth.
The exact day of Jesus' birth is difficult to establish beyond all doubt. The fact of Jesus' birth, the place, the nature, and the purpose are clearly taught in the scriptures (Matt. 1; 2). However, God did not see fit to explicitly reveal the date. We do know that Jesus was born during the reign of Herod the King (Matt. 2: 1). History informs us that this Herod died in 4 B. C. Hence, Jesus would have been born no later than 4 B. C. We also learn from the Bible that a census was being taken at the time of Jesus' birth, in fact, Joseph and Mary were at Bethlehem to enroll when Jesus was born (Luke 2: 1-7). Quirinius, the Governor of Syria, conducted this census. Based on the believed date of this census, some place Jesus' birth at 6 B. C. Some scholars believe Jesus was born in 5 B. C. In the center column reference of some versions of the King James Translation, we read regarding the time of Matthew 2, "The fourth year before the common account called Anno Domini (A. D., dm)." This date, I believe, is the product of the work of Dionysius Exiguus, a sixth century monk.
The real matter of importance. The matter of great consequence is that Jesus was born of a virgin, just as prophesied 700 years earlier (Matt. 1: 23; Isa. 9: 6). Jesus lived a sinless life and died a sacrificial death (Heb. 4: 15; Matt. 26: 28). Jesus claimed to be the Son of God and proved that claim by many undeniable miracles (John 20: 30, 31).
Christians celebrate the glorious death and resurrection of Jesus each Lord's Day when they observe the Lord's Supper (Matt. 26: 26-29, Acts 20: 7). Jesus is the truth, the way, and the life (John 14: 6). This same Jesus who experienced such a humble birth is coming back as the exalted judge of all men (Matt. 25: 31-46).
