Q7. Whence then arises the wickedness of man’s nature?
A. From the fall and disobedience of our first parents, Adam and Eve: hence is our nature so corrupt that we are all conceived and born in sin.
Romans 5:12; 18:19; Psalm 51:5; Genesis 5:3

Q8. Are we so corrupt that we are not at all apt to do well, and are prone to all vice?
A. Indeed we are, except we are regenerated by the Holy Spirit.
John 3:5; Genesis 6:5; Job 14:4; 15:16; Isaiah 53:6
