Chat: You are praying that God will give you revelation from His Word about His will regarding healing.
This is a VERY worthwhile prayer and it’s one that I use myself. I’d recommend this to anyone. Praying for revelation is a “Bible prayer” because it’s already in Ephesians 1:15-23. If Paul could pray it for the Ephesians, surely you can pray it for yourself! When a prayer like that is in the Bible, you KNOW that God will answer it because He put it in there to begin with!
So go ahead and pray that prayer! Then expect God to answer it. He may use this book to point you to certain Bible truths, though He could use many other methods as well.
