The most-likely author of Romans 13:8 is the apostle Paul. Evangelical Christians believe that Paul was chosen and commissioned by Jesus Christ to be an apostle to the Gentiles, and that he wrote several letters that are now included in the New Testament, including the book of Romans.

Paul was a dedicated follower of Jesus who had a dramatic conversion experience on the road to Damascus, which transformed him from a persecutor of Christians to a zealous preacher of the Gospel. He traveled extensively throughout the ancient world, spreading the message of Jesus and establishing Christian communities.

In Romans 13:8, Paul writes, “Owe no one anything, except to love each other, for the one who loves another has fulfilled the law.” This verse is part of a larger discussion about the Christian’s duty to love and serve others, and reflects Paul’s emphasis on the importance of living a life of love and service in obedience to God.

Evangelical Christians view Paul as a foundational figure in the development of Christian theology and believe that his writings, including the book of Romans, are inspired by God and authoritative for understanding the Christian faith. They also see his teachings on love, grace, and salvation as central to their own beliefs and practices.
