C. H. Spurgeon, as recorded in Lectures to My Students: Second Series (London: Passmore and Alabaster, 1877), HERE
Brethren, you and I must, as preachers, be always earnest in reference to our pulpit work. Here we must labour to attain the very highest degree of excellence. Often have I said to my brethren that the pulpit is the Thermopylae of Christendom:  there the fight will be lost or won. To us ministers the maintenance of  our power in the pulpit should be our great concern, we must occupy  that spiritual watch-tower with our hearts and minds awake and in full  vigour. It will not avail us to be laborious pastors if we are not  earnest preachers. We shall be forgiven a great many sins in the matter  of pastoral visitation if the people's souls are really fed on the  Sabbath-day; but fed they must be, and nothing else will make up for it.  The failures of most ministers who drift down the stream may be traced  to inefficiency in the pulpit. The chief business of a captain is to  know how to handle his vessel, nothing can compensate for deficiency  there, and so our pulpits must be our main care, or all will go awry.  Dogs often fight because the supply of bones is scanty, and  congregations frequently quarrel because they do not get sufficient  spiritual meat to keep them happy and peaceful. The ostensible ground of  dissatisfaction may be something else, but nine times out of ten  deficiency in their rations is at the bottom of the mutinies which occur  in our churches. Men, like all other animals, know when they are fed,  and they usually feel good tempered after a meal; and so when our  hearers come to the house of God, and obtain "food convenient for them,"  they forget a great many grievances in the joy of the festival, but if  we send them away hungry they will be in as irritable a mood as a bear  robbed of her whelps.
