It affirms that the spiritual development of the human race cannot be prematurely cut off, either gradually or suddenly; that every stone of offence against which we stumble is a stepping-stone to some greater good; that, at the end of days, if we choose to put it so, or, rather, in some sphere beyond the world of space and time, all the rays of progress will be summed and centred in a transcendent focus.
