Here are some evidences that the Bible is inspired (God-breathed) by God, as  declared in 2 Timothy  3:16.

1) Fulfilled prophecy. God spoke to men telling them of things  He would bring about in the future. Some of them have already occurred. Others  have not. For example, there were more than 300 prophecies concerning Jesus  Christ’s first coming 2,000 years ago. There is no doubt that these are  prophecies from God because of manuscripts and scrolls dated before the birth of  Christ. These were not written after the fact. They were written beforehand.  Scientific dating proves this.

2) The unity of Scripture. The Bible was  written by approximately 40 human authors over a period of approximately 1,600  years. These men were quite diverse. Moses, a political leader; Joshua, a  military leader; David, a shepherd; Solomon, a king; Amos, a herdsman and fruit  picker; Daniel, a prime minister; Matthew, a tax collector; Luke, a medical  doctor; Paul, a rabbi; and Peter, a fisherman; among others. The Bible was also  written under a variety of circumstances. It was written on 3 different  continents, Europe, Asia, and Africa. Yet, the great themes of Scripture are  maintained in all the writings. The Bible does not contradict itself. There is  no way, apart from God the Holy Spirit supervising the writing of the Bible,  that this could have been accomplished.

Contrast this with the Islamic  Koran. It was compiled by one individual, Zaid bin Thabit, under the guidance of  Mohammed’s father-in-law, Abu-Bekr. Then in A.D. 650, a group of Arab scholars  produced a unified version and destroyed all variant copies to preserve the  unity of the Koran. The Bible was unified from the time of its writing. The  Koran had to be unified through the editing of men.

3) The Bible  presents its heroes truthfully with all of their faults and weaknesses. It does  not glorify men as other religions do about their heroes. When you read the  Bible, you realize that the people it describes have problems and do wrong just  as we do. What made them great was that they trusted in God. One example is  David. David is described as “a man after God’s own heart” (1 Samuel 13:14). Yet,  David committed adultery (2 Samuel  11:1-5) and murder (2 Samuel  11:14-26). This could have been left out of Scripture to hide these details  of David’s life. But God included these things.

4) Archaeological  findings support the history recorded in Scripture. Though many unbelieving  people throughout history have tried to find archaeological evidence to disprove  what is recorded in the Bible, they have failed. It is easy to say that  Scripture is untrue. Proving it to be untrue is a different story. It has not  been done. In fact, in the past the Bible contradicted the current “scientific”  theories, only to be proven later to be in fact true. A good example is Isaiah 40:22, which  declared that God “sits on the circle of the earth” long before scientists  claimed the earth was flat.

The Bible’s claims of being from God should  not be understood as arguing in a circle or by circular reasoning. The testimony  of reliable witnesses – particularly of Jesus, but also of others such as Moses,  Joshua, David, Daniel, and Nehemiah in the Old Testament, and John and Paul in  the New Testament – affirm the authority and verbal inspiration of the Holy  Scriptures. Consider the following passages: Exodus 14:120:1; Leviticus 4:1; Numbers 4:1; Deuteronomy  4:2; 32:48Isaiah 1:10, 24; Jeremiah  1:11; Jeremiah  11:1–3; Ezekiel 1:31  Corinthians 14:37; 1  Thessalonians 2:13; 2 Peter  1:16–21; 1 John  4:6.

Also of interest are the writings of Josephus, an historian who  recorded much of the history of Israel during the first century. In this he  records some events which coincide with Scripture. Beware though, his writings  are rather lengthy. Considering the evidence given, we have no choice but to  accept the Bible as being from God (2 Timothy  3:16).
