It is true that a Christian who lives in tepidity still regularly -- in appearance at least -- fulfils his duties. He will indeed get down on his knees every morning to say his prayers. He will go to the Sacraments every year at Easter and even several times during the course of the twelve months. But in all of this there will be such a distaste, so much slackness and so much indifference, so little preparation, so little change in his way of life, that it is easy to see that he is only fulfilling his duties from habit and routine.
