J.C. Ryle from his classic work, Holiness (as published in Faithfulness and Holiness: The Witness of J. C. Ryle, p. 117):
It has long been my sorrowful conviction that the standard of daily life among professing Christians in this country has been gradually falling. I am afraid that Christ-like charity, kindness, good-temper, unselfishness, meekness, gentleness, good-nature, self-denial, zeal to do good, and separation from the world, are far less appreciated than they ought to be, and than they used to be in the days of our fathers.
Into the causes of this state of things I cannot pretend to enter fully, and can only suggest conjectures for consideration. It may be that a certain profession of religion has become so fashionable and comparatively easy in the present age, that the streams which were once narrow and deep have become wide and shallow, and what we have gained in outward show we have lost in quality. It may be that the vast increase of wealth in the last twenty-five years have insensibly introduced a plague of worldiness, and self-indulgence, and love of ease into social life. What were once called luxuries are now comforts and necessaries, and self-denial and “enduring hardness” are consequently little known. It may be that the enormous amount of controversy which marks this age has insensibly dried up our spiritual life. We have too often been content with zeal for orthodoxy, and have neglected the sober realities of daily practical godliness. Be the causes what they may, I must declare my own belief that the result remains. There has been of late years a lower standard of personal holiness among believers than there used to be in the days of our fathers. The whole result is that the Spirit is grieved! And the matter calls for much humiliation and searching of heart.
