I believe one of the most significant issues that we face in our culture today is the misunderstanding, or lack of understanding, of the inspiration, inerrancy, and authority of Scripture. Without a correct understanding of these three ideas, it is nearly impossible for anyone to be convinced of the Truth of God.
The Inspiration of Scripture
Scripture is the Word of God. It was written by men chosen by God, inspired by the Holy Spirit, for the encouragement, teaching, and correction of early churches, churches today, and the believers that made them up. We see this in 2 Timothy 3:16-17 (ESV), which says, “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.” If the Bible is breathed out by a perfect, holy God, then it should be viewed as the ultimate authority and incapable of having any error. I’ve heard it said before that if God cannot uphold His own Word, then He is not a God who should be trusted. The truth of God’s Word correlates directly with His own character.
The Inerrancy & Authority of Scripture
Psalm 33:4 says, “For the word of God is upright, and all his work is done in faithfulness.” We see how God’s Word and God's work are wedded together in His character. Again, we see this in Psalm 18:30, which says, “This God–His way is perfect; the word of the Lord proves true; He is a shield for all those who take refuge in Him.” Because of the perfection and faithfulness of God, we can trust in the inerrancy of His very Word. Therefore, His Word should have total authority. Benjamin B. Warfield says that “The trustworthiness of the Scriptures lies at the foundation of trust in the Christian system of doctrine, and is therefore fundamental to the Christian hope and life.”
God’s Word is tied to His character, therefore it has all authority.
If we do not have a foundational understanding of the authority of God’s Word, then we will be tossed by every idea that our culture throws at us, and Ephesians 4:14 gives us the reason: “so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes.” This is why it is so important that our pastors and shepherds, and us as Christians, hold fast to the inerrancy and authority of God’s Word.
God’s Word is tied to His character, therefore it has all authority. Because God is holy, then His Word is inerrant, and it is true. What is truth? Truth is something factual, absolute, and unchanging; conforming to a standard. In John 17:17 we see how God's Word is described in this way, “Sanctify them in the truth; your word is truth.” This verse talks about the inerrancy, steadfastness, and absoluteness of Scripture, as well as the sufficiency of Scripture to sanctify believers.
By truly understanding the word of God, a person cannot be left unchanged if they diligently apply it to their lives. The Word of God is living and active, as it says in Hebrews 4:12, “For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.”
