20 And he cried to the Lord, "O Lord my God, have you brought calamity even upon the widow with whom I sojourn, by killing her son?" 21 Then he stretched himself upon the child three times and cried to the Lord, "O Lord my God, let this child's life[1] come into him again." 22 And the Lord listened to the voice of Elijah. And the life of the child came into him again, and he revived. 23 And Elijah took the child and brought him down from the upper chamber into the house and delivered him to his mother. And Elijah said, "See, your son lives."

Commentary on 1 Kings 17:17-24
(Read 1 Kings 17:17-24)
Neither faith nor obedience shut out afflictions and death. The child being dead, the mother spake to the prophet, rather to give vent to her sorrow, than in hope of relief. When God removes our comforts from us, he remembers our sins against us, perhaps the sins of our youth, though long since past. When God remembers our sins against us, he designs to teach us to remember them against ourselves, and to repent of them. Elijah's prayer was doubtless directed by the Holy Spirit. The child revived. See the power of prayer, and the power of Him who hears prayer.
