I do not think that all those who choose wrong roads perish; but their rescue consists of being put back on the right road. A sum can be put right: but only by going back till you find the error and working it afresh from that point, never by simply going on. Evil can be undone, but it cannot 'develop' into good. Time does not heal it. The spell must be unwound, bit-by-bit, with 'backwards mutters of dissevering power' - or else not. It is still 'either-or.' If we insist on keeping Hell (or even Earth), we shall not see Heaven: if we accept Heaven we shall not be able to retain the smallest and most intimate souvenirs of Hell.
