Just as certain muscles in the body of an athlete need to be trained through repeated use before he can excel at his sport, our perceptive powers have to be trained through use in applying Bible principles.
Sportistam atkārtoti un regulāri jātrenē noteiktas muskuļu grupas, lai viņš sasniegtu ievērojamus panākumus savā sporta veidā. Savukārt mums jāvingrina prāts, liekot tam izmantot Bībeles principus.
