"To the question, 'should one preach doctrine?' the Puritan answer would have been, 'Why? What else is there to preach?' Puritan preachers were not afraid to bring the profoundest theology into the pulpit if it bore on their hearer's salvation...doctrinal preaching certainly bores the hypocrite, but it is only doctrinal preaching that will save Christ's sheep. The preacher's job is to proclaim the faith, not to provide entertainment for unbelievers. In other words, to feed the sheep and not amuse the goats." - Dr. J. I. Packer - A Quest For Godliness - The Puritan Vision of the Christian Life
