It's  so counter intuitive to be a fool, but that is what Pastor Paul is inviting us into.  We think we are wise and so we miss Jesus. So be a fool in the world's eyes and you will start to see clearer.

1 Corinthians 1:21 For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe.
