The preacher appears to have been desirous of teaching the beautiful truth, that a mind preoccupied, and inhabited by Divine thoughts, cannot entertain an evil visitor, but is compelled to betake himself to flight, by the strong expulsive power of Divine affections. He commenced, by describing Satan as a vast and wicked, although invisible spirit,—somehow, as Milton might have described him; and the preacher was not unacquainted with the grand imagery of the “Paradise Lost,” in which the poet describes the Evil One, when he tempts, with wandering feet, the dark, unbottomed, infinite abyss, and, through the palpable obscure, seeks to find out his uncouth way. Christmas described him, as spreading his airy flight on indefatigable wings, determined to insinuate himself, through the avenues of sense, to some poor soul, and lure it to destruction. And, with this end, flying through the air, and seeking for a dwelling-place, he found himself moving over one of those wide Welsh moors, the preacher so well knew, and had so often travelled; and his fiery, although invisible glance, espied a young lad, in the bloom of his days, and the strength of his powers, sitting on the box of his cart, driving on his way to the quarries for slate or lime. `“‘There he is,’ said Satan; ‘his veins are full of blood, his bones are full of marrow. I will cast my sparks into his bosom, and set all his passions on fire; I will lead him on, and he shall rob his master, and lose his place, and find another, and rob again, and do worse; and he shall go on from worse to worse, and then his soul shall sink, never to rise again, into the lake of fire.’ But just then, as he was about to dart a fiery temptation into the heart of the youth, the evil one heard him sing, “‘Guide me, O Thou great Jehovah, Pilgrim through this barren land; I am weak, but Thou art mighty, Hold me by Thy powerful hand; Strong deliverer, Be Thou still my Strength and Shield.’ ‘Oh, but this is a dry place,’ said the fiery dragon as he fled away.
