1CO 9:24

24 When people run in a race, they all run, but only one of them wins the race and as a result gets a prize. You certainly know that [RHQ]. So, [just like] runners [exert themselves fully to win a race] [MET], [you should exert yourselves fully to do the things that God wants you to do], in order that you may receive the reward [that God wants to give you].
