What is the theme of the book of Romans?

Answer 1

Romans was intended to convey the message of the righteousness of God and how it is revealed and vindicated, and how mankind can access it through faith in Christ. It is a presentation of the plan of salvation.
The Apostle Paul wrote it because the apostles were dying out and there had been heresy in the early Church. The Apostle Paul actually was a Roman citizen and he wanted his fellow citizens to believe in the Lord Jesus Christ. Hope this helps you! God bless!

Answer 2

Paul wrote this letter to introduce him self to the Church of Rome while planning a speaking tour to Spain. It is a summary of his teachings about humanitys self destructitive way of life and how they can be healed and transformed through accepting the ways of Jesus Christ.

Answer 3

Paul, in concluding his remarks to the Christians in Rome, notes and praises their obedience: "For you obedience has become known to all (Romans 16:19).

Throughout his letter to the Romans, Paul never waivers in teaching that faith produces obedience to God's Word. The major thrust throughout his message is that, "the mind set towards the flesh is hostile toward God: for it does not subject itself to the law of God, for it is not even able to do so; and those who are in the flesh cannot please God" (Romans 8:7-8).

Paul wanted the Romans to know that only a 'new heart' - which is the core of the New Testament - can enable one to obey God from the heart!!
