Mark is thought to have been the first Gospel written. Jesus took God to nations other than the Jews. That was a major deal! Mark’s job was to convince Jews and Gentiles alike that Jesus was the planned “Messiah,” "Savior of the World" and that he did all that he was supposed to do. He was the "Son of Man" (all mankind, not just the Jews). What resulted was a message that "You can Count on God and Jesus", and that he chose people that he could count on to do what they needed to do. They would pass on the Gospel to other people that could also be counted on! Can God count on you?
