St. Francis de Sales - That We Must Be Faithful, Both on Great and Small Occasions

...Be ready then, my child, to bear great afflictions for your Lord, even to martyrdom itself; resolve to give up to Him all that you hold most precious, if He should require it of you;--father, mother, husband, wife, or child; the light of your eyes; your very life; for all such offering your heart should be ready.

But so long as God's Providence does not send you these great and heavy afflictions; so long as He does not ask your eyes, at least give Him your hair.

I mean, take patiently the petty annoyances,
the trifling discomforts,
the unimportant losses which come upon all of us daily;
for by means of these little matters, lovingly and freely accepted, you will give Him your whole heart, and win His.

I mean the acts of daily forbearance,
the headache, or toothache, or heavy cold;
the tiresome peculiarities of husband or wife,
the broken glass,
the loss of a ring,
a handkerchief,
a glove;
the sneer of a neighbour,
the effort of going to bed early in order to rise early for prayer or Communion,
the little shyness some people feel in openly performing religious duties; and be sure that all of these sufferings, small as they are, if accepted lovingly, are most pleasing to God's Goodness,
Which has promised a whole ocean of happiness to His children in return for one cup of cold water.

And, moreover, inasmuch as these occasions are for ever arising, they give us a fertile field for gathering in spiritual riches, if only we will use them rightly...
