"The sinner who is to be renewed through repentance is often described in the Word of God as being submerged in a deep sleep. The distinctive feature of such persons is not necessarily their manifest depravity. It is rather the absence of an active, heartfelt, and selfless desire for pleasing God, together with a resolute aversion for everything that is sinful. Piety is not the primary object of their concern and labor. They are concerned about many other things, but are absolutely indifferent to the matter of their own salvation and are not aware of the danger they are in. They are neglectful of a good and righteous life, and lead a life that is cold to faith, although this life may sometimes be outwardly irreproachable."
