525. Most of those who enter the other life from the Christian world bring with them this belief that they can be saved by mercy apart from means, and pray for that mercy; but when examined they are found to believe that entering heaven is merely gaining admission, and that those who are let in are in heavenly joy. They are wholly ignorant of what heaven is and what heavenly joy is, and consequently are told that the Lord denies heaven to no one, and that they can be admitted and can stay there if they desire it. Those who so desired were admitted; but as soon as they reached the first threshold they were seized with such anguish of heart from a draught of heavenly heat, which is the love in which angels are, and from an inflow of heavenly light, which is Divine truth, that they felt in themselves infernal torment instead of heavenly joy, and struck with dismay they cast themselves down headlong. Thus they were taught by living experience that it is impossible to grant heaven to any one from mercy apart from means.
