We often repeat such sayings (spiritual teachings/axioms, words of the saints, Scripture) from habit and from a rather superficial grasp of their meaning. We think we are uttering them from the depths of our soul, but that’s not the case at all, as we find out later when we try to put them into practice. You say it’s all the same to you, whatever the sauce God puts you in. Come now, you know perfectly well in what sauce He has put you in, in what the state and condition of life; tell me, is it all the same to you? You are not unaware either that He wants you to satisfy that daily duty about which you write to me; still, it is not all the same to you. Oh! How subtly self-love insinuates itself into our feelings, however devout these appear to be. –St Francis de Sales a letter to Madame Brulart friend to St Jean de Chantal.
