Paul was confident that he would be released from prison soon and would have the opportunity to personally visit the Philippians. His mind and heart were prepared for whatever course he faced. If his life were to end, he was confident of a home in heaven away from the troubles and trials of earth. However, if he were permitted to continue to live, there would be many more opportunities to bear spiritual fruit for the Lord. He was confident that he would, indeed be released and return to Philippi to contribute to their work.
The Philippians were encouraged whether Paul returned or not, to remain faithful and united in the gospel of Christ. He urged them to be of one spirit and one mind in their faith of the gospel and not to fear persecution from their enemies.
