This is the story of a shy yet rebellious son of a school principal, born with a hoarse voice, and yet God called him to preach to thousands. 
 
Dr. Paul Lee Tan responed to God's call at 15.  One night, he dared to pray for Solomon-like wisdom.  But instead of wealth and IQ, God gave him "largeness of heart" (1 Kings 4:29)
 
Through a lifetime of joys and sorrow, the 80 years of Dr. Tan's life (so far) is a testimony of God's grace.  He taught an estimated half a million people worldwide - without being sensational.  Countless souls were saved and believers edified. 
 
Dr. Tan simply applied the principles of literal hermeneutics to Bible Prophecy - which is on-fourth of the Bible.  Believing in the imminent return of Christ, he was "always abounding in the work of the Lord" (1 Cor. 15:58)
