Here is a beautiful quote from a great Saint of God Most High: Saint Benedict of Nursia the author of that famous and most ancient Rule for the early Christian Ascetics: The Rule of Saint Benedict.
“If we do not venture to approach men who are in power, except with humility and reverence, when we wish to ask a favour, how much must we beseech the Lord God of all things with all humility and purity of devotion? And let us be assured that it is not in many words, but in the purity of heart and tears of compunction that we are heard. For this reason prayer ought to be short and pure, unless, perhaps it is lengthened by the inspiration of divine grace.”
– Benedict of Nursia (c. 480-543), The Rule of St. Benedict, Ch. XX
