If it can be shown that the four Gospels – Matthew, Mark, Luke and John – present an accurate record of the life and ministry of Jesus, then Jesus Himself becomes an argument in support of the truth of the Bible. If the Bible has been shown to be reliable, this line of reasoning is no longer circular, but rational. In other words, what the Bible records about Jesus, including what He says about God, human nature, salvation and the Old Testament record, can then be trusted.
What does Jesus say about God’s Word? He says, “the Scripture cannot be broken” (John 10:35, NIV), thus testifying to the authority of the Bible. In Matthew 5:17, Jesus said, “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,” meaning that Jesus believed and trusted in the Old Testament “Law” and “Prophets.” Jesus also said, “It is written: ‘Man does not live on bread alone, but on every word that comes from the mouth of God'” (Matthew 4:4). Space does not allow a thorough investigation of the views of Jesus on the Bible, but it is sufficient here to note that He believed God spoke through the Bible, He overtly upheld belief in several Old Testament stories, and revered the Bible as holy and authoritative.
The cornerstone of Christian belief is the resurrection of Christ. Even Paul the Apostle admitted that if the resurrection did not happen, Christian faith “is futile; you are still in your sins” (1 Corinthians 15:17). In this sense, making a case for the truth of the resurrection also makes a case for the truth claims of Jesus and, in turn, the reliability and truth of the Bible.
