Conversation so far:
who wrote the epistle of ephesians and to whom was it written
The Book of Ephesians was addressed “To the saints who are in Ephesus, and are faithful in Christ Jesus” and was written while Paul was in prison.
What other books besides Ephesians did the apostle Paul write while he was in prison
In addition to Ephesians, Paul wrote Philippians, Colossians, and Philemon while in prison.

Question: Who were Philippians for?
Self-contained rewrite: To whom did Paul dedicate the book of Philippians
