We just learned about Paul's letter to the church in Ephesus
Another letter Paul wrote was to a church in a town called Philippi, a city in Greece.
In this letter, Paul was giving instructions to people about how to live, to obey God and to serve him.
A famous part of the book of Philipians is:
Therefore God exalted him to the highest place and gave him the name that is above every name, that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue acknowledge that Jesus Christ is Lord, to the glory of God the Father.
