May the grace and peace and mercy of the Lord God of Abraham be upon the child of your friend.
Have you considered fasting?
Elijah and the Widow's son.
And it came to pass after these things, that the son of the woman, the mistress of the house, fell sick; and his sickness was so sore, that there was no breath left in him. And she said unto Elijah, What have I to do with thee, O thou man of God? art thou come unto me to call my sin to remembrance, and to slay my son? And he said unto her, Give me thy son. And he took him out of her bosom, and carried him up into a loft, where he abode, and laid him upon his own bed. And he cried unto the Lord, and said, O Lord my God, hast thou also brought evil upon the widow with whom I sojourn, by slaying her son? And he stretched himself upon the child three times, and cried unto the Lord, and said, O Lord my God, I pray thee, let this child's soul come into him again. And the Lord heard the voice of Elijah; and the soul of the child came into him again, and he revived. And Elijah took the child, and brought him down out of the chamber into the house, and delivered him unto his mother: and Elijah said, See, thy son liveth. And the woman said to Elijah, Now by this I know that thou art a man of God, and that the word of the Lord in thy mouth is truth.

Then were there brought unto him little children, that he should put his hands on them, and pray: and the disciples rebuked them. But Jesus said, Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven.
Matthew 19:13-14
