Characteristics required in prayer…

Seven characteristics are required in prayers. Prayer should be faithful, in accordance with the scripture: “Whatever you pray for, believe that you already have it, and it will be yours.” (Mark 11:24) then prayer should be pure, after the example of Abraham, who drove the birds away from his sacrifice. (Genesis 15:11) Third, it should be just. Fourth, it should be heartfelt, since “the heartfelt prayer of a just person works very powerfully.” (James 5:16) fifth, it should be humble. Sixth, it should be fervent (these last two characteristics you see in the mustard seed.) And seventh, it should be devout.
— Saint Bernard of Clairvaux  (1090-1153)

The divine scriptures…

Great is the profit of the divine Scriptures, and all-sufficient is the aid which comes from them….   For the divine oracles are a treasury of all manner of medicines, so that whether it be needful to quench pride, to lull desire to sleep, to tread under foot the love of money, to despise pain, to inspire confidence, to gain patience, from them one may find abundant resource.
 –Saint John Chrysostom (347-407)
