The intent of the sport analogies in the last paragraph of chapter 9 is to expound upon one of Jesus’ more challenging forewarnings. “Make every effort to enter through the narrow door, because many, I tell you, will try to enter and will not be able to. Once the owner of the house gets up and closes the door, you will stand outside knocking and pleading, ‘Sir, open the door for us.’
“But he will answer, ‘I don’t know you or where you come from.'” (Luke 13:24-25)
Knowing the frightful reality of this prophecy, Apostle Paul puts this in words the Corinthians can relate to. The Isthmian Games were like the Olympic Games, both part of the four sacred games, featuring athletic, musical, and equestrian competitions, with winners receiving a dried celery wreath and, later, a pine wreath. The prize was really the recognition and acclaim from the judges and their peers.
How serious-minded am I about following Jesus? What is my heart’s desire? What prize do I desire? Is Jesus my prize? Or do I not care that he might say, “I do not know you.” Am I fixing my eyes on Jesus as I run the race? Or do I turn to look at someone or something else?
