Repentance is the true turning of our life to God, a turning that arises from a pure and earnest fear of Him; and it consists in the mortification of the flesh and the renewing of the Spirit.

Though Satan instills his poison, and fans the flames of our corrupt desires within us,we are yet not carried by any external force to the commission of sin, but our own flesh entices us, and we willingly yield to its allurements
