“I observe, first of all, that, according to Scripture, the self-denial which is the test of our faith must be daily. ‘If any man will come after Me, let him deny himself, and take up his cross daily, and follow Me.’ [Luke 9:23] It is thus St. Luke records our Saviour’s words. Accordingly, it seems that Christian obedience does not consist merely in a few occasional efforts, a few accidental good deeds, or certain seasons of repentance, prayer, and activity; a mistake, which minds of a certain class are very apt to fall into. This is the kind of obedience which constitutes what the world calls a great man, i.e. a man who has some noble points, and every now and then acts heroically, so as to astonish and subdue the minds of beholders, but who in private life has no abiding personal religion, who does not regulate his thoughts, words, and deeds, according to the law of God. Again, the word daily implies, that the self-denial which is pleasing to Christ consists in little things. This is plain, for opportunity for great self-denials does not come every day. Thus to take up the cross of Christ is no great action done once for all, it consists in the continual practice of small duties which are distasteful to us.
“[…] Rise up then in the morning with purpose that (please God) the day shall not pass without its self-denial, with a self-denial in innocent pleasures and tastes, if none occurs to mortify sin. Let your very rising from your bed be a self-denial; let your meals be self-denials. Determine to yield to others in things indifferent, to go out of your way in small matters, to inconvenience yourself. […] This is one great end of fasting. […] Make some sacrifice, do some distasteful thing, which you are not actually obliged to do, (so that it be lawful,) to bring home to your mind that in fact you do love your Saviour, that you do hate sin, that you do hate your sinful nature, that you have put aside the present world. […] Try yourself daily in little deeds, to prove that your faith is more than a deceit.” – John Henry Newman, Parochial and Plain Sermons, Volume 1, Sermon 5
