the ability to choose. Since human beings are born spiritually dead in sin (Ephesians 2:1), they do not have free will in spiritual matters. By nature they cannot choose to believe in Christ or do those doings which are pleasing to God (Romans 8:7-8). By nature human beings have free will to make choices in outward matters: what to eat, what to wear, to work, to marry, etc.
