Ep.43 - Run the race with certainty

1Co 9:22  To the weak became I as weak, that I might gain the weak: I am made all things to all men, that I might by all means save some. 
1Co 9:23  And this I do for the gospel's sake, that I might be partaker thereof with you. 
1Co 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. 
1Co 9:25  And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible. 
1Co 9:26  I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: 
1Co 9:27  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.
