The most-likely author of the book of Galatians is the Apostle Paul. In Galatians 1:1, Paul introduces himself as the author of the letter to the Galatians, and this is widely accepted by evangelical Christians.

Paul, formerly known as Saul of Tarsus, was a Pharisee who persecuted the early Christian church before encountering Jesus on the road to Damascus. After this encounter, he became a fervent follower of Christ and dedicated his life to spreading the gospel to both Jews and Gentiles.

In Galatians 4:4-5, Paul writes about the incarnation of Jesus Christ, emphasizing that God’s timing was perfect in sending his Son into the world. This passage highlights the sovereignty of God and the redemptive work of Jesus, central themes in evangelical Christian theology.

Overall, evangelical Christians view the Apostle Paul as a foundational figure in the early church and a key contributor to the New Testament. His writings, including the book of Galatians, are highly respected and influential in shaping evangelical beliefs and practices.
