Now mine eyes shall be open, and mine ears attent unto the prayer that is made in this place. (2 Chronicles 7:15)

Be careful for nothing, but in every thing, by prayer and supplication, with thanksgiving, let your requests be made known unto God. (Philippians 4:6)

When thou criest, let thy companies deliver thee; but the wind shall carry them all away; vanity shall take them: but he that putteth his trust in me shall possess the land, and shall inherit my holy mountain. (Isaiah 57:13)

The Lord redeemeth the soul of his servants: and none of them that trust in him shall be desolate.

Judaism, Christianity, Islam, Buddhism -- every religion believes in prayer for healing. Some call it prayer, some call it cleansing the mind. The words or posture may vary. But in times of illness, all religions look toward their source of authority.
