But we are told that there are angels "which kept not their first estate," and which are reserved "unto judgment of the great day;" namely, Satan and his apostate subordinates. Fallen though they be, their brightness "has not lost all its original splendour;" but they exercise their high powers in tempting and seducing to his eternal ruin man, whom Satan by his wiles has already crushed, and robbed of his original innocence. Let us strive against the tempter, the deceiver, who lays luxury, licentiousness, gold, fame, power, before his willing slaves, trying them on every point, and inducing too many to fall irrecoverably. But God's thoughts are higher than our thoughts, or than the thoughts of man's crafty adversary; and in wisdom he devised that mighty scheme, through which rescue and pardon are freely granted to all who accept the invitation of the Redeemer, "Come unto me, all ye that labour and are heavy laden, and I will give you rest;" "All," he says, "that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out," John vi. 37. Jesus is the Conqueror, and death is swallowed up in victory. Flee, then, from the city of destruction; and though the slough of despond or the valley of humiliation be before, press forward, awakened sinner, to the heavenly Jerusalem! on that let your thoughts be placed. 4. _Comparison._--The direct comparison of one object with another, with a view towards the acquisition of information, is exercised by man alone of all animals; but that superficial and involuntary comparison which leads to the simple _distinction_ of things, as of land from water, or trees from houses, is common both to animals and man. _Choice_ supposes the exercise of comparison, in a low degree, and this a bird displays in the selection of a spot for its nest, and the beaver in that of a site for its dam and village. In both these cases, however, _instinct_ impels to the labour, and supplies the place of experience. 5. _Knowledge of Cause and Effect._--A knowledge of the connexion between cause and effect is the result of experience alone. We thus accumulate a number of facts, and by reasoning upon those facts, can infer with certainty what would be the result under such or such contingencies. That brutes gain information to a certain extent by experience is very plain. We have seen a monkey break nuts by hammering them upon a stone--we have seen the orang try to pick the lock of its door with a bit of stick--we know instances of horses disengaging themselves from their headstall, unbolting the stable door, and making off to the pasture; a cat in our possession was accustomed to leap up and open the latch of the kitchen door, whenever she wished to enjoy a stroll. We might multiply examples, but so many will suggest themselves to the reader's mind, that we may spare ourselves the task.
