According to this doctrine [of total depravity], man in his present condition since the fall is so polluted with a principle of evil that every aspect of his being and personality is affected by it. The term depravity refers to the moral disposition or inclination of fallen man’s nature toward evil and against good. This principle of sin and moral pollution is such that man is by nature opposed to what is true and righteous. The inclination of his heart, the delight of his soul, the orientation of his will is toward wickedness. Nothing compels him to sin. He sins because he loves it. He revels in it. He has no taste for God, but relishes evil and pursues it with voluntary zeal.
