The white butterfly would come and go. As the breeze blew, the butterfly steered along on its stream. There was no set pattern for flight. Freedom of motion made the butterfly look to the world too random. The butterfly knew what the world could not and flew rightly.
Joh 3:8 The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit.
