What the Bible says about Elijah's Exhaustion
(From Forerunner Commentary)
God sent an angel, possibly the Word, the Angel of the Lord (cf. verse 7; Genesis 22:15; Exodus 3:2), to give Elijah food and drink (verse 5). He needed revitalized after expending so much energy in God's service. But after eating, Elijah did a typically human thing—he went back to sleep (verse 6)! How often have we studied deeply into God's Word, consuming meaty material, then sunk back into spiritual drowsiness after we were satisfied?
