There is only one prayer that is ever answered—the prayer to know God. He is our one real need.
Prayer unanswered is prayer that is not truly unselfish, prayer for something less than silent surrender to the perfect Father. But when through Science we become completely conscious of our spiritual being at one with our Father, there simply is nothing that can harm us—no disease, no lack of good, no power of evil.
All that God can give is His own perfect self. If we are praying for physical health, for material evidence of supply, companionship, or peace, we are in some degree praying for deceptions that the Father's immaculate good already excludes. (All that Mind creates and knows is spiritual, faultless.) His freeing answers come as pure spiritual consciousness of Him.
