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 2

2:17 When Jesus heard it, he saith unto them, They that are whole have no need of the physician, but they that are sick: I came not to call the righteous, but sinners to repentance.
