And surely our own personal experience daily corroborates this view. There may be intellectual conviction and controversial triumph without any spiritual enthusiasm. Sermons may be clever, powerful, convincing, and yet, unless the Spirit's power be sought, and an unction from on high be vouchsafed, no spiritual harvest can be expected. St. Peter's sermon, if viewed from a human standpoint, could no more have been expected to succeed than the Master's. The one new element, however, which now entered into the combination, explains the difference. The Spirit was now given, and men therefore hearkened to the servant where they had turned a deaf ear to the Master. It is a lesson much needed for our generation, especially in the case of the young, and of our Sunday-school system. The religious instruction of youth is much more carefully looked after than it used to be. Primers, handbooks, elementary commentaries, catechists' manuals, are published in profusion, and many think that provided a Sunday or day school distinguishes itself in the examination list, which is now the one great educational test, religious knowledge has been secured. The contrast between St. Peter's success and our Lord's failure warns us that there is a vast difference between religious life and religious knowledge. The most irreligious people, the most bitter opponents of Christianity, have been produced by schools and systems where religious knowledge was literally crammed down the throats of the children in a hard, mechanical, unloving style. But let there be no mistake. I do not object to organised religious instruction. I think, in fact, that a vast amount of Sunday-school teaching is utterly worthless for want of such organization. Our Sunday-school system will, in fact, be thoroughly inefficient, if not useless, as a system, till every Sunday-school has its teachers' meeting, presided over by a competent instructor, who will carefully teach the teachers themselves in a well-ordered, systematic course. But after all this has been done, we must still remember that Christianity is something more than a system of doctrine, or a Divine scheme of philosophy, which can be worked up like Aristotle's _Ethics_ or Mill's _Logic_. Christianity is a Divine power, a power which must be sought in faith, in humiliation, and in prayer; and till the Holy Ghost be duly honoured, and His presence be humbly sought, the finest system and the most elaborate organizations will be found devoid of any fruitful life and vigour.
