How Can I Know that the Bible Is the Inerrant Word of God?

The Christian philosopher and apologist Gordon Clark once wrote, "Because God is sovereign, God's authority can be taken only on God's authority. As the scripture says, 'Because He could swear by no one greater, He swore by Himself' (Hebrews 6:13)" (from God's Hammer, p. 39). His point was that confirmation of authority comes from higher authority. However, there can be no authority higher than God by which to confirm what He says. By His own authority, therefore, He declares His own truth and authority. 

The thoughtful person sees this and asks, "But isn't this circular reasoning?" And it is. Yet, we can see the impossibility of an alternative if we ask a parallel question: "How can you prove logic without presupposing logic as the basis for its proof?" 

The thoughtful Christian might ask whether the unbeliever would be convinced by that argument. And the obvious answer is that an unbeliever would not be convinced. Yet we must deny that his disbelief is based on a reasonable doubt. On the contrary, his rejection would arise from his own presuppositions against God's authority. Those presuppositions are the inherent nature of unbelief (Romans 1:18). 

On the other hand, we know that there are many Christians who receive the Bible as God's word, and that it is necessarily, therefore, inerrant. I am one of those Christians. Yet that belief did not arise from a consideration of a chain of logical arguments or archeological verifications. 

So, from where did my belief come? 

Clark quotes from the Institutes of John Calvin: "It is, therefore, such a persuasion as requires no reason; such a knowledge as is supported by the highest reason and in which the mind rests with greater security and constancy than in any reasons; in fine, such a sense as cannot be produced but by a revelation from Heaven" (I. vii.5). By "revelation," Calvin meant no such thing as a voice whispering in the believer's ear. Rather, in the process of effectual calling, the Holy Spirit causes the man's spirit to recognize the truth of the Scriptures as he reads them or hears them preached. 

This concept was picked up later (1646) in the writing of the Westminster Confession of Faith (I:5), the doctrinal statement of the world's Presbyterians: "We may be moved and induced by the testimony of the Church to an high and reverent esteem of the holy Scripture; and the heavenliness of the matter, the efficacy of the doctrine, the majesty of the style, the consent of all the parts, the scope of the whole (which is to give all glory to God), the full discovery it makes of the only way of man's salvation, the many other incomparable excellencies, and the entire perfection thereof, are arguments whereby it doth abundantly evidence itself to be the Word of God; yet, notwithstanding, our full persuasion and assurance of the infallible truth and divine authority thereof, is from the inward work of the Holy Spirit, bearing witness by and with the Word in our hearts." The Westminster divines added to Calvin's argument that Scripture provides good reasons for recognizing it as the Word of God. Yet the unbeliever suppresses his awareness of those qualities (Romans 1:18). He cannot recognize them exactly because of his unbelief (I Corinthians 2:14). He cannot be argued out of his unbelief, because his unbelief is a matter of sin, not ignorance. 

The case here demonstrates why we never see an apologetical situation in the New Testament in which Jesus or the Apostles ever argued for acceptance of Scriptural proofs. Even when Jesus faced Satan and when Paul preached to the pagan philosophers of Athens, each argued from Scripture as his starting point, not as a subsidiary point requiring proof. 

We must remember the promise of God: "So shall My Word be, that goes out of My mouth; it shall not return to Me empty, but it shall accomplish that which I purpose, and shall succeed in the thing for which I sent it" (Isaiah 55:11). God promises success to His word, not to our attempts to appeal to the fallen intellect of the unbeliever. "Of His own will He brought us forth by the word of truth, that we should be a kind of firstfruits of His creatures" (James 1:18). There has never been any other way by which God has converted His elect (Romans 10:8-15).
