Just as crucially, if all Scripture is breathed out by God, then there is a unity to be found across the pages of the Bible. Without minimizing the differences of genre and human authorship, we should nevertheless approach the Bible expecting theological distinctives and apparent discrepancies to be fully reconcilable.
The unity of Scripture also means we should be rid, once and for all, of this “red letter” nonsense, as if the words of Jesus are the really important verses in Scripture and carry more authority and are somehow more directly divine than other verses. An evangelical understanding of inspiration does not allow us to prize instructions in the gospel more than instructions elsewhere in Scripture. If we read about homosexuality from the pen of Paul in Romans, it has no less weight or relevance than if we read it from the lips of Jesus in Matthew. All Scripture is breathed out by God, not just the parts spoken by Jesus.
God’s gracious self-disclosure comes to us through the Word made flesh and by the inscripturated word of God. These two modes of revelation reveal to us one God, one truth, one way, and one coherent set of promises, threats, and commands to live by. We must not seek to know the Word who is divine apart from the divine words of the Bible, and we ought not read the words of the Bible without an eye to the Word incarnate. When it comes to seeing God and his truth in Christ and in Holy Scripture, one is not more reliable, more trustworthy, or more relevant than the other. Scripture, because it is the breathed-out word of God, possesses the same authority as the God-man Jesus Christ. Submission to the Scriptures is submission to God. Rebellion against the Scriptures is rebellion against God. The Bible can no more fail, falter, or err, than God himself can fail, falter, or err.
