Man and Sin by Piet Schoonenberg (1964) 2.3 B

Summary of text [comment] page 80

The inclination to evil is a sequel to sin. The human (who was not undergone an interior conversion under the influence of grace) will always be self-centered and selfish. These will guide his first actions. These actions will have consequences. The person will look for some way out. His heart will then harden into pride and despair.
