Free will is "corrupted nature's deformed darling, the Pallas or beloved self-conception of darkened minds"

Temptation is like a knife, that may either cut the meat or the throat of a man; it may be his food or his poison, his exercise or his destruction

I will not judge a person to be spiritually dead whom I have judged formerly to have had spiritual life, though I see him at present in a swoon (faint)as to all evidences of the spiritual life. And the reason why I will not judge him so is this -- because if you judge a person dead, you neglect him, you leave him; but if you judge him in a swoon,(faint) though never so dangerous, you use all means for the retrieving of his life.

Let no man think to kill sin with few, easy, or gentle strokes. He who hath once smitten a serpent, if he follow not on his blow until it be slain, may repent that ever he began the quarrel. And so he who undertakes to deal with sin, and pursues it not constantly to the death.
