So is Time by Eternity

"Eternity is a perpetual duration, which has neither beginning nor end; time has both. Those things we say are in time that have beginning, grow up by degrees, have succession of parts; eternity is contrary to time, and is therefore a permanent and immutable state; a perfect possession of life without any variation; it comprehends in itself all years, all ages, all periods of ages; it never begins; it endures after every duration of time, and never ceases; it does as much outrun time, as it went before the beginning of it: time supposes something before it; but there can be nothing before eternity; it were not then eternity. Time has a continual succession; the former time passes away and another succeeds: the last year is not this year, nor this year the next. We must conceive of eternity contrary to the notion of time; as the nature of time consists in the succession of parts, so the nature of eternity in an infinite immutable duration. Eternity and time differ as the sea and rivers; the sea never changes place, and is always one water; but the rivers glide along, and are swallowed up in the sea; so is time by eternity."
