Now he that knows that he has a Father gracious to him through Christ, truly knows God; he knows also that God cares for him, and calls upon God; in a word, he is not without God, as the heathen. For devils and the ungodly are not able to believe this article: the forgiveness of sins. Hence, they hate God as an enemy, call not upon Him, and expect no good from Him. Augustine also admonishes his readers concerning the word "faith," and teaches that the term "faith" is accepted in the Scriptures not for knowledge such as is in the ungodly but for confidence which consoles and encourages the terrified mind.
Augsburg Confession, 1530
