This humility may be traced incidentally in other regions of the Christian life. Thus he speaks of the possibility at least of his being among those who might "shrink with shame from Christ in His coming." He does not disdain to write as if, in hours of spiritual depression, there were tests by which he too might need to lull and "persuade his heart before God."[110] (3) St. John again has a boundless faith in prayer. It is the key put into the child's hand by which he may let himself into the house, and come into his Father's presence when he will, at any hour of the night or day. And prayer made according to the conditions which God has laid down is never quite lost. The particular thing asked for may not indeed be given; but the substance of the request, the holier wish, the better purpose underlying its weakness and imperfection, never fails to be granted.[111] (4) All but superficial readers must perceive that in the writings and character of St. John there is from time to time a tonic and wholesome _severity_. Art and modern literature have agreed to bestow upon the Apostle of love the features of a languid and inert tenderness. It is forgotten that St. John was the son of thunder; that he could once wish to bring down fire from heaven; and that the natural character is transfigured not inverted by grace. The Apostle uses great plainness of speech. For him a lie is a lie, and darkness is never courteously called light. He abhors and shudders at those heresies which rob the soul first of Christ, and then of God.[112] Those who undermine the Incarnation are for him not interesting and original speculators, but "lying prophets." He underlines his warnings against such men with his roughest and blackest pencil mark. "Whoso sayeth to him 'good speed' hath fellowship with his _works_, those wicked _works_"[113]--for such heresy is not simply one work, but a series of works. The schismatic prelate or pretender Diotrephes may "babble;" but his babblings are wicked words for all that, and are in truth the "works which he is doing."
