The Magi are the three kings who travel to worship Jesus when He is born. They crossed great distances to find Him and show Him the honor He deserved. In doing so, they met Herod who was immediately fearful of Christ and wanted Him destroyed. This led to the Slaughter of the Innocents and the flight of Jesus, Mary and Joseph to Egypt. Had the Magi not gone seeking Jesus, Herod might not have found out about Christ until He was older. The Magi, of course, meant no harm and avoided Herod on their way out of Bethlehem so that they would not lead Herod’s men to Jesus.
The Magi were likely not actually kings. Instead, they would have been ancient astronomers and mathematicians who noticed unusual events in the skies. They were among the first to meet Jesus, and they were both foreigners and scientists. From the very beginning, Jesus was Lord of all nations. He was sent to the Jews, but when He came to Earth, even those who did not know the prophecies of the Old Testament or had heard of the Messiah knew that something extraordinary had happened. The three unnamed Magi were an early clue that the gentiles would find their way into Christ’s grace.
