This is NOT, I repeat, NOT an easy read.
Part of that is the dated language, part of it is the edition of the book. Some strange editing here.
I am giving it four stars because there was enough of a really great, sound biblical message throughout that I know the problem was probably me and not Newton.
A few of my favorite quotes:
from pg.172:
"We often complain of losses; but this expression is rather improper. Strictly speaking, we can lose nothing, because we have no real property in anything. Our earthly comforts are lent us; and when recalled, we ought to return and resign them with thankfulness to Him who has let them remain so long in our hands."
from pg. 294:
"Your constitution, your situation, your temper, your distemper, all that is either comfortable or painful in your lot, is of His appointment. The hairs of your head are all numbered: the same power which produced the planet Jupiter is necessary to the production of a single hair, nor can one of them fall to the ground without His notice, any more than the stars can fall from their orbits. In providence, no less than in creation, He is Maximus in minimus. Therefore fear not; only believe. Our sea may sometimes be stormy; but we have an infallible Pilot, and shall infallibly gain our port."
(Bold type added by me for last sentence; as I felt it was particularly profound and a great summary of the passage.)
Recommended, but possibly look for a different edition.
