“In preaching, not only is the minister giving us doctrinal and moral instruction (though that is involved), but God is actually killing us and making us alive, writing us out of the “in Adam” story and into his new script of the new creation.
Throughout the Scriptures, God’s Word through the lips of sinful ambassadors is spoken of as “the power of God for salvation” (Rom 1:16,cf. Mark 8:38. 1 Cor 1:18, 24; 2:9) and effective in every mission for which it is sent (Isa 55:10-11). The Word of God is inherently “living and active” (Heb 4:12), judging and justifying (vv.13-14). Peter tells us that we have been “born again …..through the living and abiding word of God……..And this word is the good news that was preached to you” (1 Peter 1:23,25). The gospel does not merely tell us how to “get saved”, as though it were an instruction manual (another command); it is the means through which God actually saves sinners.”
