889 Jesus, You have given me to know and understand in what a soul's greatness consists: not in great deeds but in great love. Love has its worth, and it confers greatness on all our deeds. Although our actions are small and ordinary in themselves, because of love they become great and powerful before God.
890 Love is a mystery that transforms everything it touches into things beautiful and pleasing to God. The love of God makes a soul free. She is like a queen; she knows no slavish compulsion; she sets about everything with great freedom of soul, because the love which dwells in her incites her to action. Everything that surrounds her makes her know that only God himself is worthy of her love. A soul in love with God and immersed in Him approaches her duties with the same dispositions as she does Holy Communion and carries out the simplest tasks with great care, under the loving gaze of God. She is not troubled if, after some time, something turns out to be less successful. She remains calm, because at the time of the action she had done what was in her power. When it happens that the living presence of God, which she enjoys almost constantly, leaves her, she then tries to continue living in lively faith. Her soul understands that there are periods of rest and periods of battle. Through her will, she is always with God. Her soul, like a knight, is well trained in battle; from afar it sees where the foe is hiding and is ready for battle. She knows she is not alone-God is her strength.
