Time is the very lens through which ye see—small and clear, as men see through the wrong end of a telescope—something that would otherwise be too big for ye to see at all. That thing is Freedom: the gift whereby ye most resemble your Maker and are yourselves parts of eternal reality. But ye can see it only through the lens of Time, in a little clear picture, through the inverted telescope. It is a picture of moments following one another and yourself in each moment making some choice that might have been otherwise.
