A significant line of evidence supporting the Bible’s trustworthiness is seen in the harmonious relationship of the Old Testament to the New Testament. These books agree with each other and complement each other to an extent not seen in any other literature of their kind. They were written over a 1500 year period with God using at least 40 human authors. Basically the Bible is divided into two testaments. The Old Testament includes, among other things, the laws God wanted His people to follow until Christ instituted His church. The New Testament includes the law God wants us to follow today.
The Old Testament is broken down into three divisions: Historical, Poetical and Prophetic. The New Testament is divided into four categories: The Gospels, Acts, Epistles, and elevation. The Historical Books of the Old Testament are the story of the rise and fall of the Hebrew Nation. The Poetical Books belong to the Golden Age of the Hebrew Nation. The Prophetical Books belong to the fall of the Hebrew Nation. The New Testament covers the life of Christ in the Gospels, the acts of the Apostles in Acts, the writings and teachings of Christ’s apostles in epistles, and the revelation made to John in Revelation.
The Bible clearly states that the Word of God is complete. The clearest example of this idea is in Galatians 1:6, “I am astonished that you are so quickly deserting the one who called you by the grace of Christ and are turning to a different gospel – which is really not gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ. But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let him be eternally condemned. As we have already said, so now I say again: If anybody is preaching to you a gospel other than what you accepted, let him be eternally condemned.
