Every combatant in the public games is temperate in all things: they, indeed, that they may obtain a corruptible, but we, that we may obtain an incorruptible crown.

I am able to do all things through Christ who strengthens me.

I have fought the good fight, I have finished the race, I have kept the faith:

For I determined not to know any thing among you but Jesus Christ, and him crucified.
