When fatigue walks in, faith walks out. When you are tired, you change. You talk differently. You think differently. You assess life differently. Always inaccurately.
Accept your personal and unique sleep requirements. Make a habit of going to bed every night at the same time. Your life depends on it.
“And he said unto them, Come ye yourselves apart into a desert place, and rest a while: for there were many coming and going, and they had no leisure so much as to eat.”
