Paul wrote the Book of Colossians and was from the city of Tarsus. He had been known as Saul in his early life. Before becoming a Christian, Paul was a Pharisee who persecuted Christians. After he became a Christian, he traveled several times throughout the Roman Empire telling people about Jesus.
Paul wrote this letter to the believers in the Asia Minor city of Colossae. The main purpose of this letter was to defend the gospel against false teachers. He did this by praising Jesus as the image of God, sustainer of all things, and head of the church. Paul wanted them to understand that only Christ is needed for God to accept them.
