It is important for us to understand that the authors of each of the Gospels had a particular audience in mind when they wrote. They therefore presented Jesus in a specific way that would appeal to that audience. Matthew wrote to a predominantly Jewish readership. He presents Jesus as the promised Messiah/King in the lineage of Abraham and David. Luke is focused more on the Greek-speaking world, specifically addressed to Theophilus (Luke 1:1–4), and Jesus is presented as the Savior of all mankind, both Jew and Gentile. John has a wider focus than the rest of the Gospels, as he writes to the whole world, presenting Jesus as both Creator (John 1:1–4) and Savior (John 3:16–19).
The Gospel of Mark was apparently written by John Mark (Acts 13:5, 13; 1 Pet. 5:13), from the recollections of Peter. In this sense, it could be referred to as the “Gospel according to Peter, as recorded by Mark.” He writes with the Roman audience in mind. As a result, Jesus is presented as a man of power and action. He emphasizes the mighty deeds of Jesus—demonstrating His power over disease, demons, and death.
