The church must be Word-oriented: that is, God's people must always be attentive and obedient to Scripture. Scripture is God's Word of constant address to them, and woe betide them if they disregard it (see 2 Kgs. 22:8-20; 2 Chr. 36:15-16; Isa. 1:19-20; Jer. 1:23-26; Rev. 2:4-7, 15-17, etc.). God's people must learn to 'tremble at his word' (Ezra 9:4; Isa. 66:5), listening, learning, and laying to heart; believing what he tells them, behaving as he directs them, and battling for his truth in a world that denies it.
Preaching, as an activity of letting texts talk, alerts Christians to the fact that God is constantly addressing them and enforces the authority of Scripture over them. The church must live by God's Word as its necessary food and steer by that Word as its guiding star. Without preaching, however, it is not conceivable that this will be either seen or done (246).
I heartily agree with J. I. Packer, and pray that the Lord would grant that more of our preaching would be “an activity of letting texts talk.”
