Natural Man

"For the preaching of the cross is to them that perish foolishness; but unto us who are saved it is the power of God."

God knows and understands what this world thinks of the gospel. Believers should understand this, and never be offended when others laugh, mock, and scorn the Bible. Laughing at foolishness is a natural reaction. Natural and Spiritual are two different realms. 

"But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned." 

"God is a Spirit..." The spiritual realm is where you will find Him when you are seeking for Truth.
