A recently read a fresh definition of what the word "preaching" means in assication to biblical sermon delivery.
"Preaching is a function of the revelation of God.
Preaching exists because God has spoken and wants man to know what He has said.
Preaching communicates the living and powerful Word of God as we receive it in the Bible.
Preaching is central to a primary strategy in the cosmic war of god against the forces of evil.
Preaching is central to the biblical witness and the calling to ministry.
Preaching the Word of god calls for careful interpretation of the biblical text as the primary source of revelational meaning."
