“If assurance is not of the essence of saving faith, and it can be lost because of sin, sensitive persons will inevitably scrape their consciences raw until they find clues and, as Calvin warned, there will be no satisfaction with evidences;……there will never be enough to secure the soul’s confidence.”
-Michael Horton
“
There is nothing then that can satisfy the conscience in respect of the guilt of sin, but the blood, and death, and resurrection of Jesus Christ.” -Thomas Goodwin
