Daily Luther: Look Nowhere Else But to the Scriptures!
There is no other enduring way of preserving our doctrine and our faith than the physical or written Word, poured into letters and preached orally; for here we find it stated clearly: “Scripture! Scripture!” But Scripture is not all spirit, about which they drivel, saying that the Spirit alone must do it and that Scripture is a dead letter which cannot impart life. But the fact of the matter is that, although the letter by itself does not impart life, yet it must be present, and it must be heard or received. And the Holy Spirit must work through this in the heart, and the heart must be preserved in the faith through and in the Word against the devil and every trial. Otherwise, where this is surrendered, Christ and the Spirit will soon be lost. Therefore do not boast so much of the Spirit if you do not have the revealed external Word; for this is surely not a good spirit but the vile devil from hell. The Holy Spirit, as you know, has deposited His wisdom and counsel and all mysteries into the Word and revealed these in Scripture, so that no one can excuse himself. Nor must anyone seek or search for something else or learn or acquire something better or more sublime than what Scripture teaches of Jesus Christ, God’s Son, our Savior, who died and rose for us.
