In Matthew 5:17-18, the Lord said:
Matt. 5:17-18 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18 For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished.
Here the Lord Jesus demonstrates His commitment to the full authority and infallibility of the Old Testament. The Lord Jesus goes to the most insignificant detail of the Scriptures and affirms that they will not by any means pass away. This demonstrates that He believed in the inspiration, inerrancy as well as the preservation of Scripture. John MacArthur notes, “Here Christ was affirming the utter inerrancy and absolute authority of the OT as the word of God—down to the smallest stroke or letter.” Matthew Henry comments on this place:
Heaven and earth shall come together, and all the fulness thereof be wrapped up in ruin and confusion, rather than any word of God shall fall to the ground, or be in vain. The word of the Lord endures for ever, both that of the law, and that of the gospel. Observe, The care of God concerning his law extends itself even to those things that seem to be of least account in it, the iotas and the tittles; for whatever belongs to God, and bears his stamp, be it ever so little, shall be preserved.
The same is asserted for the Lord Jesus’ teaching, and by extension to His teaching through the Apostles, in Matthew 24:35. His words will not fail to accomplish that which He intends. They are the words of God and are more powerful than the cosmos itself. It would be easier for the whole cosmos to vanish away than the Words of our God to pass away.
Words of men are known to contain lies, but the words of God have no lies whatsoever in them (Titus 1:2) because this God is a God of truth (Isa. 65:16; John 14:6; 17:17). Paul says in Romans 3:4:
By no means! Let God be true though every one were a liar, as it is written, “That you may be justified in your words, and prevail when you are judged.”
God is always true and every time when He opens His holy mouth and when He speaks to His people through His God-breathed Word. Words of men may contain errors, but the God of the Word cannot lie and His words are always true.
Believing the doctrine of inerrancy is the natural implication if we affirm that the Bible is the Word of God. Affirming the doctrine of inerrancy is simply submitting to the absolute Lordship of God, even in thinking about His Word and following the Messiah’s view of Scripture. Since we are Christians, we, therefore, should share the same view of Jesus on Scripture, which was clearly that they were inerrant and infallible, and fully trustworthy.
The Scriptures are the sole infallible rule of faith for the Church. Since they are Theopneustos, God-speaking (Matt 22:31; 2Tim 3:16-17; 2Pet 1:20-21), they are, by definition, ultimate in authority, for there can be no higher authority than God Himself. All other rules of faith, creeds, councils, or anything else produced by the Church herself, is subject to the ultimate c...
