....And a Sermon, Too.

John Piper on The Place of Preaching in Worship

....the Word of God is to come teaching the mind and reaching the heart; showing the truth of Christ and savoring the glory of Christ; expositing the Word of God and exulting in the God of the Word.

That is what preaching is. And that is why it is so prominent in worship. It is not a mere work of man. It is a gift and work of the Holy Spirit.
