"For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe."   (1 Corinthians 1:21)

"How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? And how shall they preach unless they are sent? AS it is written: "How beautiful are the feet of those who preach the gospel of peace, who bring glad tidings of good things!"  (Romans 10:14-15)
