Mark is the earliest of the Gospels and contains much of the teachings of Peter. This Gospel presents Jesus as the man of power, the strong and active Son of God; its climax is reached when Peter makes his great confession, “You are the Christ.”

Mark 9

9:42 And whosoever shall offend one of these little ones that believe in me, it is better for him that a millstone were hanged about his neck, and he were cast into the sea.
