We have to transform the sinful "reality"of the world to the the teachings of the Gospel and God's revealed will. Not conform the Word to the world. 

Fr. Cameli, Sant Theresa of Lisieux actually said this: “Holiness consists simply in doing God's will, and being just what God wants us to be.” Her  radical message: If we’re not holy, forget the excuses and rationalisations - "it's too difficult" "God can't expect this from me"; "our culture drags us down"; "it would be impossible to live this way"; etc. etc.  If we're not holy, i.e. not following God's will, it's because we don’t want to be. Find the commandments difficult in the circumstances of your life? Turn up; trust God; and let Him do the work. Live a joyful life of sacrifice in the circumstances we find ourselves in. She also said: “I can nourish myself on nothing but truth” and: “A soul in a state of grace has nothing to fear of demons who are cowards.”
