beating the air...

Everyone who competes in the games goes into strict training.

They do it to get a crown that will not last;

but we do it to get a crown that will last forever.

Therefore I do not run like a man running aimlessly;

I do not fight like a man beating the air.

No, I beat my body and make it my slave so that after I have preached to others,

I myself will not be disqualified for the prize.

1 Corinthians 9:25-27, NIV

what is "a crown that will not last" and what is "a crown that will last forever?"

if i am struggling to get what Paul threw away considering them rubbish, it's just ridiculous....

always, i am confused.... what was Paul thinking?

i am trying to understand something beyond my understanding, but it's like beating the air...
