"I would ye should understand, brethren, that the things which happened unto me have fallen out [turned out] rather unto the furtherance of the gospel" (Philippians 1:12).
In this verse, Paul tells the Christians in Philippi not to worry about all the things that they had heard had befallen him. And those "things" included great afflictions and infirmities.
Paul wrote this epistle while bound in a Roman prison. At that point he was a seasoned warrior of the gospel, having endured every conceivable hardship and human affliction imaginable. If you have studied Paul’s life, you know the kinds of things he had faced: shipwrecks, beatings, buffetings, tauntings, mockings, persecutions, hunger, thirst, nakedness, defamation of character. Everywhere Paul went, it seemed, he was met by affliction, trouble and sorrow.
