Sometimes we may ask God for success, and He gives us physical and mental stamina. We might plead for prosperity, and we receive enlarged perspective and increased patience, or we petition for growth and are blessed with the gift of grace. He may bestow upon us conviction and confidence as we strive to achieve worthy goals.
Happiness doesn't depend on any external conditions, it is governed by our mental attitude.
True prayer is neither a mere mental exercise nor a vocal performance. It is far deeper than that - it is spiritual transaction with the Creator of Heaven and Earth.
