1 Corinthians 2:10-13
Ancient Greek philosophers spent a tremendous amount of self reflection. The axiom know thyself is ancient, and yet it still sways over philosophers as both a warning and a mission. Paul says that the reason Christians are a mystery to others is that they can never truly understand what motivates us – our life, our code of ethics, and even our reward. This is because we are not only moved by our own spirit, but by the spirit of God.
