Preaching is indispensable to Christianity. Without preaching a necessary part of its authenticity has been lost. For Christianity is, in its very essence, a religion of the Word of God. No attempt to understand Christianity can succeed which overlooks or denies the truth that the living God has taken the initiative to reveal himself savingly to fallen humanity; or that his self-revelation has been given by the most straightforward means of communication known to us, namely by a word and words; or that he calls upon those who have heard his Word to speak it to others.
–John Stott, Between Two Worlds
