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 13

13:8 For nation shall rise against nation, and kingdom against kingdom: and there shall be earthquakes in divers places, and there shall be famines and troubles: these are the beginnings of sorrows.
