1.) Feed your belly with the scriptures (word of God) — The scriptures satisfy the natural cravings and desires of this life that may not be bad in and of themselves, but have the ability to distract us from the greater good if we are given to them disproportionately.
2.) Fill your stomach with the scriptures (word of God) — Our spirit needs food that abounds in vitamins & minerals. Eating spiritual junk food leaves us nutrient deprived and incapable of enduring the race.
Proverbs 13:25 — The righteous eats to the satisfying of his soul, but the stomach of the wicked shall be in want.
