Just as the Lord Jesus Christ raised children from the dead when he walked the Earth, the Lord worked through Elijah the Prophet to miraculously bring the widow’s child back to life long ago.
1 Kings 17:20-22
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 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.
