Do you believe in human freewill? Two basic approaches have been debated for thousands of years. First, some Christians believe in libertarian freedom. Here, freewill means people really could choose to act differently than they do. Sally chose to follow God, but she could have chosen to follow Baal instead.

Imagine a pianist who could say “I love you” to his lover by playing a song at the piano. The better the pianist and the better he knew his lover, the more compelling this love song would be. In some ways it might be even better than talking or writing a letter.

Before we’ve even learned to walk, we humans begin fighting for freedom; first, in play but then more seriously as we object to authority, consequences, expectations, guilt, pain, doubt, anxiety, and death—the freedom wish list is very long.
