According to Ripley's Believe it or Not, the oldest known bird was called the Archaeopteryx. According to scientists, this ancient bird was so clumsy it could not control its own flight. It simply flew into the air and went wherever the wind blew it.
Many Christians are that way. They have no sense of direction and purpose.
Because of that, they go where the wind blows them.
