If you lay your Bible next to the bed of a sick person, will your Bible heal him or her? Will the Bible levitate from off of your coffee table, if you pray hard enough? If you wave your Bible over the head of a sinner three times, will he be saved by its powers?
Of course not.
So when Christians speak of the Bible, God's Word, having incredible power, what do we mean?
If you ask an evangelical Christian to answer this question, this is what he will probably say: "Of course the actual book---the leather binder and the pages---have no power; it is the meaning of the words inside that have power. It is the message of the Gospel that has power. It is the message that God offers the free gift of salvation, if the sinner will only make the decision to reach out and accept God's offer of eternal life."
If you ask an orthodox (confessional) Lutheran Christian this question, this is the answer you will hear: "Of course the actual book, the binder and pages, have no power, but the words on those pages have incredible power. And its not just the meaning of the words that has incredible power...it is the words of God themselves that have power!
When Christ calmed the wind and the waves on the Sea of Galilee, he did so by the power of his words. When Christ raised Lazarus from the dead, he did so by the power of his words. And when Christ's words, the Scriptures, are spoken or read today, God grants faith, saves sinners, and washes away their sins.
It isn't just the meaning of his words that have power, dear evangelical brothers and sisters, the power of the Bible is in Christ's actual words! The words of Christ, referred to collectively as the Word, really and truly do have supernatural...heavenly powers!
This is why the Christian Church since the time of the Apostles has taught that God saves in Holy Baptism. It isn't magical baptismal water that saves...it is the supernatural power of God's Word, spoken at the time of the application of the baptismal water, that saves.
