Philippians is the sixth of Paul's Epistles and the eleventh book in the New Testament. It was written around 62 AD, to the Church at Philippi in Greece, whilst Paul was a prisoner in Rome.
Paul had founded the Church in Philippi four or five years before he wrote this letter, and they had been generous to him, sending money to help him in his ministry. When they heard that Paul was in prison the Philippians sent money and a man named Epaphroditus to help him. Whilst helping Paul, Epaphroditus became ill and almost died, so Paul sent him home, along with this letter, thanking the Philippians for their help.
Paul was aware that his own death may be close as his trial would soon be at hand, but he was not discouraged; his letter is one of joy.
