One of the major issues laid against Christians is that they are using a circular argument to prove a point and therefore, they are not proving anything. They believe that Jesus Christ is true because the Scriptures talk about him, and then they argue that the Scriptures are true because Jesus Christ talked about them being true.
Is there a way of proving their truthfulness independently? Is there a way of proving the Scriptures as being true strictly on their own, without the attestation of Jesus?
In order to do this authentication one has to do a historical-archeological verification. On the pages of the Old Testament we had the story of Jericho. Now the story of Jericho has been a story that the post-Enlightenment people rejected. There was no archeological evidence for the city of Jericho and thus became the laugh for the sophisticated. Then towards the end of the 19th century, the ruins of the city of Jericho were found. Those who laughed had to change their minds and the Bible proved to be true archeologically.
Karl Barth, the great German theologian, was asked after World War II why he still believes in God. He gave a twofold answer. The first was to sing the Sunday School song, "Jesus loves me this I know, for the Bible tells me so, Little ones to him belong, they are weak but he is strong, Yes, Jesus loves me, Yes Jesus loves me, Yes Jesus loves me, the Bible tells me so." The second reason, according to Barth, was that for the past 3,000 many have sought to destroy the Jews and even though at times it looked like their enemies would succeed, God has protected them. In the Bible we have an expression that God will watch over the Jewish remnant. God has told the Israelites that they would be protected and blessed if they are faithful to him, and expelled from their land if they sin against God. If one reads the Jewish history one can see that the word of the Scriptures has come to be true even before the authentication that Jesus provided.
The other aspect is to find out if those things that Jesus said about Himself have come true. For over 75 years the Russian Communist Encyclopedia told its readers that Jesus Christ did not exist. The last publication said that he did exist but he was not God. An English journalist by the name of Frank Morison set out to prove that the resurrection did not happen. At the end of his research he wrote the book "Who Moved the Stone?," in which he documented how he became convinced that Jesus did, in fact, rise from the dead.
However, one must accept the fact that faith does hold a major importance in the Christian faith. The ancient Christian philosophers did say "I Believe in order to understand." The post-Enlightenment thinkers argue "I think, therefore, I am." In the first statement, the authority over human beings was the word of God, and thus belief was important. For our contemporaries, the supreme decision is made in our mind. If our mind cannot comprehend or fathom, then it does not exist.
The author of Hebrews wrote, "But without faith it is impossible to please God: for he that cometh to God must believe that he is and that he is a rewarder of them that diligently seek him." Hebrews 11:6 (KJV)
I often find out that people dismiss the Bible without reading it. Very few people have I encountered who could say, "I have diligently searched the Scriptures and I have concluded that they are not true." For when we come to the Scriptures we must pray that He who brought the Scriptures into existence will illumine our minds to understand them.
