He who stands upon his own strength will never stand. - Thomas Brooks

One of Satan's devices to keep poor souls in a sad, doubting, and questioning condition is causing them to be always posing and musing upon sin; to mind their sins more than their Saviour: yea, so to mind their sins as to forget and neglect their Saviour. Their eyes are so fixed upon their disease that they cannot see their remedy, though it be near; and they do so muse upon their debts that they have neither mind nor heart to think of their surety.

The giving way to a less sin makes way for the committing of a greater.

Satan, being fallen from light to darkness, from felicity to misery, from heaven to hell, from an angel to a devil, is so full of malice and envy that he will leave no means unattempted, whereby he may make all others eternally miserable with himself.
