4.  But of all the men in the whole world it is ministers who should simply, as Peter says, be clothed with humility, and that from head to foot.  And, first as divinity students, and then as pastors and preachers, we who are ministers have advantages and opportunities in this respect quite peculiar and private to ourselves.  For, while other students are spending their days and their nights on the ancient classics of Greece and Rome, the student who is to be a minister is buried in the Psalms, in the Gospels, and in the Epistles.  While the student of law is deep in his commentaries and his cases, the student of divinity is deep in the study of experimental religion.  And while the medical student is full of the diseases of animals and of men, the theological student is absorbed in the holiness of the divine nature, and in the plague of the human heart, and, especially, he is drowned deeper every day in his own.  And he who has begun a curriculum like that and is not already putting on a humility beyond all other men had better lose no more time, but turn himself at once to some other way of making his bread.  The word of God and his own heart,—­yes; what a sure school of evangelical humility to every evangelically-minded student is that!  And, then, after that, and all his days, his congregational communion-roll and his visiting-book.  Let no minister who would be found of God clothed and canopied over with humility ever lose sight of his communion-roll and pastoral visitation-book.  I defy any minister to keep those records always open before him and yet remain a proud man, a self-respecting, self-satisfied, self-righteous man.  For, what secret histories of his own folly, neglect, rashness, offensiveness, hot-headedness, self-seeking, self-pleasing vanity, now puffed up over one man, now cast down and full of gloom over another, what self-flattery here, and what resentment and retaliation there; and so on, as only his own eyes and his Divine Master’s eye can read between every diary line.  What shame will cover that minister as with a mantle when he thinks what the Christian ministry might be made, and then takes home to himself what he has made it!  Let any minister shut himself in with his communion-roll and his visiting-book before each returning communion season, and there will be one worthy communicant at least in the congregation:  one who will have little appetite all that week for any other food but the broken Body and the shed Blood of his Redeemer.  But these are professional matters that the outside world has nothing to do with and would not understand.  Only, let all young men who would have evangelical humility absolutely secured and sealed to them,—­let them come and be ministers.  Just as all young men who would have any satisfaction in life, any sense of work well done and worthy of reward, any taste of a goal attained and an old age earned, let them take to anything in all this world but the evangelical pulpit and its accompanying pastorate.
