“The Bible is inspired, but is it inerrant, that is without errors? The reason for a positive answer is simple: The Bible is the Word of God, and God cannot err; therefore, the Bible cannot err. To deny the inerrancy of the Bible one must either affirm that God can err or else that the Bible is not the Word of God.” – Norman Geisler
An interesting thought worth repeating:
“To deny the inerrancy of the Bible one must either affirm that God can err or else that the Bible is not the Word of God.”
Here’s the explanation of that from the same article by Norman Geisler:
God Cannot Err
The Scriptures declare emphatically that “it is impossible for God to lie” (Heb. 6:18, NASB). Paul speaks of the “God who does not lie” (Titus 1:2, NIV). He is a God who, even if we are faithless, “He remains faithful; He cannot deny Himself” (2 Tim. 2:13, NKJV). God is truth (see John 14:6),and so is His Word. Jesus said to the Father, “Your word is truth” (John 17:17, NKJV). The psalmist exclaimed, “The entirety of Your word is truth” (Ps. 119:160, NKJV).
The Bible is the Word of God
Jesus referred to the Old Testament as the “Word of God” which “cannot be broken” (John 10:35, NKJV). He said, “Until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished” (Matt. 5:18, NIV). Paul added, “All Scripture is God-breathed” (2 Tim. 3:16, NIV). It came “from of the mouth of God” (see Matt. 4:4, NIV). Although human authors recorded the messages, “prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit” (2 Pet. 1:21, NIV).
Jesus said to the religious leaders of His day, “You nullify the word of God by your tradition (Mark 7:13, NIV). Jesus turned their attention to the written Word of God by affirming over and over again, “It is written . . . It is written . . . It is written . . .” (see Matt. 4:4, 7, 10). This phrase occurs over ninety times in the New Testament. It is a strong indication of the divine authority of the written Word of God. Stressing the unfailing nature of God’s truth, the apostle Paul referred to the Scriptures as “the word of God” (Rom. 9:6, NASB).
The Logical Conclusion: The Bible Cannot Err
Yes, God has spoken, and He has not stuttered. The God of truth has given us the Word of Truth, and it does not contain any untruth in it. The Bible is the unerring Word of God.
