On the other hand, by deeds of charity and love, and by a life of extraordinary purity, the evil spirit may be expelled, and the soul left to the undisputed sway of the good one. He who is thus freed from the power of his evil angel has the power of seeing and hearing his good one, and of learning things incomprehensible to the generality of his race. To him the fountains of knowledge are unsealed, and he learns, while yet on earth, much that is reserved to be learned in Heaven after we have become a new order of beings, endowed with new intelligence. It is sin only that blinds our sight and darkens our minds, and, consequently, the more effectually we can free ourselves from sin the better are we prepared for the reception of knowledge. Perfect knowledge can only be attained by perfect purity, and hence perfect knowledge is perfect bliss; and the highest bliss of heaven is to perfectly understand all things. On earth, corrupted and polluted as it is by sin, there can be no perfect knowledge, and, consequently, no perfect bliss. And although there are different degrees of knowledge in Heaven, yet every degree is perfect, and affords perfect bliss so far; and, as we ascend step by step up the heavenly temple of knowledge, perfect bliss will be added to perfect bliss, and thus will we go on until we reach the summit and possess ourselves of all the blissful attributes of God himself. The more knowledge we attain on earth, provided it be applied to good, the higher will be the grade to which we will be admitted in Heaven, and consequently the more perfect our bliss there; but if it be directed towards the attainment of an end transgressing the laws of God and furthering evil, the more intense will be the sufferings in the world of punishment.
It is an incontrovertible law of natural philosophy, that not an atom of matter can be annihilated; and it is a law as applicable to the immaterial as to the material world. Every act we have ever committed, every word we have ever spoken, and every thought that has ever flitted through our minds, remains as indestructible as the throne of Omnipotence itself. Here on earth we act, speak, and think, and then forget the deeds we have done, the words we have spoken, and the thoughts we have harbored; but on the day of the final reckoning, when our spirits shall re-enter our arisen bodies, every thought, word, and deed shall recur to us as vividly as though they had taken place at that very instant. Thus every one has his whole life spread before him, takes in all at a glance, and becomes his own judge; and as his conscience approves or condemns him, so is he approved or condemned by God. And although men are accountable, yet this does not exempt their good angels from being judged also. Their course is judged, and if they have been remiss in performing the duties assigned them, and have not watched diligently over the souls committed to their charge, then they receive the reward due to their negligence; and as those souls over which they kept watch are the gainers or losers by their conduct, therefore it is permitted them to judge them, as St. Paul saith, "Know ye not that the angels are to be judged by us?"
