“You shall love the Lord your God with your whole heart, your whole soul and your whole strength.” It seems to me that the love of the heart relates to a certain warmth of affection, the love of the soul to energy or judgement of reason, and the love of strength can refer to constancy and vigor of spirit. So love the Lord your God with the full and deep affection of your heart, love him with your mind wholly awake and discreet, love him with all your strength, so much so that you would not even fear to die for love of him. As it is written: “For love is strong as death, jealousy is bitter as hell.”
St. Bernard of Clairvaux
