Moses and the prophets wrote all the books we collectively call the Old Testament (what Jesus and the apostles called the Scriptures). Moses was the first and the greatest of the prophets. Therefore, to say that “the prophets wrote the Old Testament” or to say “Moses and the prophets wrote the Old Testament” is to say the same thing. Moses set a standard for prophets that was not exceeded until the time of Jesus. The prophets did not write under their own inspiration. Rather they wrote under the inspiration of God through His Holy Spirit.
The apostles were chosen by Jesus and told His story throughout the known world of that age. They wrote the documents that comprise what we call the New Testament. The apostles did not write under their own inspiration. Rather, they wrote under the inspiration of God through His Holy Spirit.
Jesus did not write any New Testament documents for the same reason that He did not write any of the Old Testament documents - that is, He was the One doing the inspiring through His Holy Spirit.
The purpose of this blog is to praise Jesus Christ in terms familiar to those who read the Bible, and to help others become more familiar with the Bible. For those unfamiliar with the Bible, see the blog A Nonchurchgoer’s Guide to Jesus and His Kingdom.
