Yes, prayer is IMPORTANT!!! I found this at Saintly Sages.
Father Girardey offers this potpourri of thoughts on the subject of prayer:
“Whether we pray vocally or mentally, it is our heart that should speak to God.” -St. Augustine
“Prayer is the food of our soul, for on it depends our preservation in the state of grace and our eternal life in heaven.”
