17And Jesus said to them, "Follow Me, and I will make you become fishers of men."
18Immediately they left their nets and followed Him.
Mark is brief on the details when it comes to the calling of Simon, Andrew, James and John. It includes less than both Matthew and Luke (Luke of course including the most detail in this event), yet this is the core moment. Jesus calls and they immediately follow. No hesitation, no pause, no talking to their father, mother, wife, girlfriend or life coach. Four guys who have been in the fishing business all their lives (it mentions in Mark that James and John left their Dad with the hired help) it wasn't their lot in life to follow some wandering Rabbi. At least that is how it looks like.
Questions bubble up in my mind about this immediate decision to follow Jesus. Of course being a christian I know that the calling of Jesus the Christ is irresistible. Yet how do I explain this calling? How did Simon, Andrew, James and John answer it? Immediately. It is not a decision that you can take and leave in the back of your mind, or is it? Also, can someone who has decided to follow Jesus leave?
