Adam Clarke, on 1Cor 9:24

“Know you not that they that run in the race, all run indeed, but one receiveth the prize? So run that you may obtain.”

“They which run in a race run all - It is sufficiently evident that the apostle alludes to the athletic exercises in the games which were celebrated every fifth year on the isthmus, or narrow neck of land, which joins the Peloponnesus, or Morea, to the main land; and were thence termed the Isthmian games. The exercises were running, wrestling, boxing, throwing the discus or quoit, etc.; to the three first of these the apostle especially alludes. But one receiveth the prize? - The apostle places the Christian race in contrast to the Isthmian games; in them, only one received the prize, though all ran; in this, if all run, all will receive the prize; therefore he says, So run that ye may obtain. Be as much in earnest to get to heaven as others are to gain their prize; and, although only one of them can win, all of you may obtain.”
