 If you're like me and you're up in age, you have to walk and not run. But then Paul uses another metaphor called fight. He said, I fight not as one who beats the air. So we got run, walk, fight, and then the word strive in 2 Timothy 2, 5. And if a man also strive for the masteries, yet is he not crowned except he strive lawfully to compete, winning the prize. All of this requires self-control.
