The natural heart is . . .
the nursery of sin,
the magazine where all the weapons of unrighteousness lie,
full of antipathy against God,
a lesser Hell.

Morality is but nature refined — old Adam put in a 
  better dress. The garnishing of man with moral excellencies, is 
  but adorning a dead man with a garland of flowers!
  
Civility is not grace, although it is a good wall 
  against which to plant the vine of grace.
Sin is not only a defection — but a pollution. 
Sin is to the soul, as rust is to gold. 
Sin is as a stain is to beauty. 
Sin makes the soul red with guilt — and black with 
  filth!
Sin has blotted God's image and stained the orient 
  brightness of the soul.
There is more evil in a drop of sin — than in a sea 
  of affliction.
The love of sin makes sin taste sweet, and this 
  sweetness beguiles the heart, and ruins the soul. 
It is worse to love sin than to commit it. The love 
  of sin . . . 
hardens the heart,
keeps the devil in possession, and
freezes the soul in impenitency.

Despair, on account of sin, locks up the soul in 
  impenitency. Despair is irrational: the Lord "shows mercy to thousands." 
  The wings of God's mercy, like the wings of the cherubim, are stretched 
  out to every humble penitent. Although you have been a great sinner, 
  yet, if you are a weeping sinner — there is a golden scepter of mercy 
  held forth.
The sinner may live in a calm — but he will die in a 
  storm of wrath! He who lives graceless, dies peaceless.
View sin in the looking-glass of Christ's sufferings. 
  The least sin cost his blood. Jesus Christ veiled his glory and poured 
  out his soul unto death, on account of sin. Read the greatness of your 
  sin in the greatness of the Savior's sufferings, and in the depth of his 
  wounds!
God's long forbearance in not punishing of 
  sin, is no forgiveness! The longer God delays the blow — the 
  heavier it falls when he strikes!
When a man sins presumptuously, he stuffs his pillow 
  with thorns, and his head will lie uneasy when he dies.
Sin casts the soul overboard, and the loss of the 
  soul is an unparalleled loss — it can never be made up again.
