It is sometimes said that God has written two books: creation and the Bible. God has first revealed Himself through and in what He has made. This is His general revelation to all people, in that everyone has equal access to it simply by watching a sunset at the beach, standing on a mountain top, or observing the night sky.
But God has also spoken through people in history and this is known as special revelation. In special revelation, God reveals information that could not have been discovered any other way (e.g., people can’t deduce from a sunset that Jesus Christ has provided salvation for any who would place their trust in Him). As they were led by the Holy Spirit, the authors of Scripture communicated God’s words to His people (from 1405 bc to ad 95). The books we possess, from Genesis to Revelation, are God’s final and authoritative revelation to the world. No clearer word is needed and no higher authority can be appealed to.
An important corollary to this discussion is the Bible’s status of being “without error,” known as the doctrine of inerrancy. Because of God’s perfect character and the fact that He cannot lie, it follows that His revelation to us would be without error. But, you might ask, didn’t flawed and sinful human beings pen Scripture? Yes. But that is why the Holy Spirit guarded the original writings from error.
Theologian David Dockery offers a good summary of this doctrine, “When all the facts are known, the Bible (in its original writings) properly interpreted in light of which culture and communication means had developed by the time of its composition will be shown to be completely true (and therefore not false) in all that it affirms, to the degree of precision intended by the author, in all matters relating to God and his creation.” And even though none of the original manuscripts exist today, biblical scholars have sufficiently demonstrated that the Bible has been accurately and reliably preserved for us. Therefore, the Bible you can buy today is essentially the Word of God. Indeed, “All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work” (2 Tim. 3:16–17).
