Being Self Disciplined

(based on 1 Corninthians 9: 24-26)

Runners run a race,
The winner takes it all,
You must make the line,
To answer heaven's call

A runner's crown will fade,
Whilst yours will ever last,
So make your purpose clear,
And set yourself steadfast

Don't box as with the air,
Or make a muddled fight,
May all your blows be bold,
And punch with all your might.
