There are many prayers in Holy Scripture worth praying today. Some scripture is clearly a prayer. Other scripture can be converted into a prayer with slight modification.
A prayer written by Paul at the end of Romans is definitely worth praying just like it is or, if you prefer, with a minor change where the Gentiles are mentioned. Today, instead of saying “all the Gentiles,” it might be more sensible to say “all people.”
In any event, it is a powerful prayer from Paul’s heart based on his ministry and preaching. In a short prayer, he covers a lot of ground, like Jesus did with the Lord’s Prayer.
“Now to him who is able to establish you in accordance with my gospel, the message I proclaim about Jesus Christ, in keeping with the revelation of the mystery hidden for long ages past, but now revealed and made known through the prophetic writings by the command of the eternal God, so that all the Gentiles might come to the obedience that comes from faith–to the only wise God be glory forever through Jesus Christ! Amen.” (Romans 16:25-27, NIV)
