Biblical Ignorance Is Killing Believers by Dr Michael H Yeager

1 Corinthians 9:24 Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. 25.............26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air:27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
