The Bible is the one written word of God from Genesis (original creation) to Revelation (the new heavens and the new earth). There is one consistent story (creation-fall-redemption) narrated throughout the 66 books of the Bible. The four gospel accounts (Matthew, Mark, Luke, and John) are early attempts to consolidate the entire story into short summaries (“gospels” or tracts that tell the good news of God’s redemption).
The story of God and his dominion was prophesied through Isaiah in the Old Testament. In the New Testament, Mark builds upon Isaiah’s prophecy to picture Jesus as its fulfillment. In Mark’s story, when Jesus calls the disciples to follow him, he calls them to follow him personally in the work he is accomplishing.
Jesus commands his disciples, “Follow me.” Jesus calls his disciples to follow him in Mark 1:17; 2:14; and 8:34, with the first-person pronoun (me) present each time, thus indicating that their call was not a generic following of a religion or a political action committee; rather, the call was to follow Jesus Christ himself.
The personal nature of this call was made clear by Peter, who said in 10:28, “Behold, we have left everything and followed you.” The disciples left their families and jobs for this single purpose: to follow Jesus Christ. The gospel of Mark makes clear that this following of Jesus means following also the kingship mission he was accomplishing.
The gospel of Mark unfolds the relationship between Christ and his followers as beginning with the call to be in the presence of Christ but always accompanying that call with the expectation that the disciples will also join with Christ in announcing the coming of a new kingdom. The disciples are called to more than a profession of faith. They are called to join “the initiation of God’s sovereign action that brings salvation and is to end in a transformed universe.”
They are called to faith, to believe (1:14-15). Being called for Christ’s sake and for the sake of the gospel in Mark is similar to being called on account of righteousness in Matthew. Also in Mark 3:14, Jesus appointed twelve to be in his presence and to go out and preach, and, in this one verse, two controlling ideas are found: presence and practice. From the time of their calling, the disciples are called both to Christ’s presence and to the practice of obedience.
Being thus connected to the presence and practice of Christ, faithful followers are expected to suffer opposition and even persecution–just as Christ did–because they are empowered by Christ himself to continue his kingdom work. Christ explained this to his first followers, for instance, in Mark 10:29-30:
29 Jesus said, “Amen, I say to you, there is no one who has given up house or brothers or sisters or mother or father or children or lands for my sake and for the sake of the gospel 30 who will not receive a hundred times more now in this present age: houses and brothers and sisters and mothers and children and lands, with persecutions, and eternal life in the age to come.
