Paul, who had been a Pharisee, was well acquainted with the Old Testament writings and referred to them frequently in his epistles. He used them as the authority for the doctrines he expounded. He showed from the scriptures that Jesus was the promised Messiah as prophecied in the Old Testament. The following verses typify Paul's approach:
== 1Now when they had passed through Amphipolis and Apollonia, they came to Thessalonica, where was a synagogue of the Jews: 2And Paul, as his manner was, went in unto them, and three sabbath days reasoned with them out of the scriptures, 3Opening and alleging, that Christ must needs have suffered, and risen again from the dead; and that this Jesus, whom I preach unto you, is Christ. 4And some of them believed, and consorted with Paul and Silas; and of the devout Greeks a great multitude, and of the chief women not a few.
Additionally, Paul pointed out how the Old Covenant was superseded by the new and salvation was no longer by works of the Law, but through faith in the atoning sacrifice of Christ.

The old testament was written by many people like Solomon and David. The New testament was written mostly by Paul from Romans to Revelation except John 1,2, and 3. But all together God told them to so it was him.
