The four gospels are the same story, but told from different perspectives. Matthew wrote about Jesus as the King of the Jews, so there are many Old Testament connections. But Mark wrote the story for the Greeks, so we see many shades of Grecian culture in there. Luke, who was a physician by trade, wrote the story from the perspective of His humanity, so we can see the personal side of Jesus. These three are called the Synoptic Gospels, because they all tell the same story. But John, who wrote his gospel long after the rest, was writing to a new generation of believers, which included many Gentiles. So he tells the story from the perspective of Jesus’ deity, that He was indeed God, come in the flesh. Four different angles, or faces, of the gospel story.
The Prophet Ezekiel had a vision of God appearing in a whirlwind: “Also out of the midst of it came the likeness of four living creatures. And this was their appearance: they had the likeness of a man. And every one had four faces, and every one had four wings” (Ezekiel 1:5-6). This vision corresponds with Isaiah’s vision in Isaiah 6 and John’s vision in Revelation 4.
God wanted the whole world to know about His Son, Jesus Christ, that’s why those He chooses are so diverse in this world. God’s grace is multi-faceted.
