As I have been studying Mark the past few months, one of the most striking elements of the Gospel is what I call,"The Abruptness of Jesus." From the very first verse Jesus, the Son of God, appears on the scene and begins to speak and act like He is and has sovereign divine authority. Mark does make a small effort to try to prepare us for Him with a few verses on John the Baptist's ministry, who was the one sent to prepare the people for the coming of the Messiah. But Mark is even abrupt with John's appearance and then his disappearance.

Mark 1:4,
"John appeared, baptizing . . ." Then just 10 verses later,
"Now after John was arrested, Jesus came into Galilee, proclaiming the Gospel of God." (Mark 1:14 ESV)
There is no long list of the genealogy of Jesus' ancestors. There is no narrative of Jesus' birth. We don't find any information about what was going on in the world previous to His arrival on the scene. We aren't even told immediately where Jesus, the man has come from. But we are told up front who He is. The significance of Who Jesus is, is the main theme of Mark's Gospel in fact.
So the World is just going on as it always had. People are eating, drinking, getting married, and dying. And then God abruptly steps into history. He does not ask our permission to just show up and begin to reveal His authority, He does not have to. Does He abruptly interrupt the lives and plans of people? You bet He does, just ask the families of Simon, Andrew, James, and John (Mark 1:16-20). Does He try not to offend and make waves with the status quo? He actually does the very opposite by commanding people to "Repent and accept the reality that there is a new kingdom taking over, and I am the New King."
Mark writes this way about Jesus because he wants to help us to see that this is who Jesus is, and this is often how we experience Him in our lives. He abruptly steps in and changes our direction, or gives us a major challenge, or calls us to stop, or change, or turn around. He calls us to submit and if we don't submit, we find ourselves, just "kicking against the goads." We open up our Bibles and expect to find some comforting words for a discouraging day. But what we end up finding is that we are having our hearts examined, and being horrified by what we see there. Or we begin a relationship with someone we hope will greatly encourage and build us up, when what ends up happening is the relationship costs us much more then we were hoping to gain from it. We wake up from our slumber and find that the world we were trying to control to fit our designs is being ruled by another King, who has much different plans for us.
So how are we to respond? What are we to do? Well, the wisest step would be to do exactly what the King said,
"Repent and believe in the Gospel" (Mark 1:15). And what is the Gospel? It's just the best news that you will ever hear. This King who abruptly entered history and sovereignly interrupted your life,
"came not to be served, but to serve, and to give his life as a ransom for many" (Mark 10:45). He came to set you free from the master you were serving, an evil master who would have destroyed you. Our freedom came at the cost of His life, which He willingly laid down for us.

Now, we belong to Him, but we don't have to work to earn His favor, we already have it and will forever have it. We just simply trust Him, believe what He says, and work our faith out in love for Him and for others. If this has happened to us, we will love Him, and the more we love Him, the more life we will experience, and the more love we will have for others. We will truly become who we were created to be, which will bring an ever increasing sense of fulfillment and joy, which will never end no matter what may come; be it tribulation, sickness, or death.
