1 Corinthians 9:26

So I do not run uncertainly or box like one who hits only air.

Therefore I do not run like a man running aimlessly; I do not fight like a man beating the air.

Therefore I run in such a way, as not without aim; I box in such a way, as not beating the air;

So I run straight to the goal with purpose in every step. I am not like a boxer who misses his punches.

I don't know about you, but I'm running hard for the finish line. I'm giving it everything I've got. No sloppy living for me!

So then I am running, not uncertainly; so I am fighting, not as one who gives blows in the air:

So I do not run aimlessly, nor do I box as though beating the air;

Therefore I run thus: not with uncertainty. Thus I fight: not as one who beats the air.

So I do not run uncertainly or box like one who hits only air.
