Great quote from Charles Spurgeon on sermons:
I would sooner preach the dullest sermon that was ever preached than preach the most brilliant that was ever spoken if I could by that poor sermon lead you quite away from myself to seek the Lord Jesus Christ. That is the one thing I care about. Will you never gratify me by enquiring after my Lord and Master? I long to hear you say, "What is the man talking about? He speaks about a Savior; we will have that Savior for ourselves. He talks about pardon through the blood of Christ; he speaks about God coming down among men to save them; we will find out if there is any reality in this pardon, any truth in this salvation. We will seek Jesus, and find for ourselves the blessings which are reported to be laid up in him." If I heard you all saying this I should be ready to die of joy.
(Sermon 1698, Dec 24th, 1882)
