In the first chapter of Mark, immediately (εὐθύς) is used nine times. For example, we read how Jesus calls his disciples and they immediately leave vocation and family. The chapter concludes with the story of Jesus speaking to the leper and he is immediately healed.
Why would the Spirit move Mark to write the text in such a manner (2 Peter 1:21)? In the healing of the leper the point seems obvious, the Spirit wants us to see Jesus' authority over sickness. But what do we make of the immediate response of the disciples? Is the Spirit merely challenging us to respond to Christ's call in a similar manner? Or could this be another indication of Christ's authority?
In John's Gospel, Jesus cries out, "Lazarus, come out" and a dead man walks out of his grave. In Isaiah 55 we read, “For as the rain and the snow come down from heaven and do not return there but water the earth, making it bring forth and sprout, giving seed to the sower and bread to the eater, so shall my word be that goes out from my mouth; it shall not return to me empty, but it shall accomplish that which I purpose, and shall succeed in the thing for which I sent it." God's word brings life. God's word accomplishes God's purpose. It will succeed in accomplishing His will. Could it be that Mark is directing our attention to Christ's sovereign authority?
Paul reminds the Ephesians (Ephesians 2:1) that they were dead in their trespasses and sins. How did they come to life? Paul describes that, "faith comes by hearing and hearing through the Word of Christ" (Romans 10:17). How do spiritually dead men walk? When Christ comes calling! As believers, we should be amazed at the authority of Jesus. We should be overwhelmed by the grace of Jesus.
