Train yourself to be godly. For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come. 
-1 Timothy 4:7-8

In order to excel in any sport, one must spend hours and hours in training. It is also true of artists and musicians. No one achieves excellence in any field without tremendous self-discipline, hours of rigorous training and a willingness to suffer great hardship in order to achieve the goals he has set for himself.
