1. Fellow workers (21-23)
Paul was a disciple-maker. He traveled around with the young men he was discipling. One of his most promising young disciples was Timothy. He wrote about Timothy, 'I have no one else like him...' (Php 2:20). There were others, too. Tertius was Paul's amanuensis. Paul was writing from Corinth, where he enjoyed the hospitality of Gaius.
2. The mystery long hidden (25-27)
Glory and praise to God who establishes us by the gospel and by the proclamation of Jesus Christ to all nations. In his great wisdom he has revealed to us the mystery kept secret until the coming of Jesus: God is the God of all people. He wants all people of every nation to repent, believe, and obey the gospel. God's heart is for the whole world. He calls us who know him to go and make disciples of all nations, teaching them the obedience that comes from faith.
Application: Lord, hasten the day when all people repent, believe, and obey the gospel.
One Word: That all nations might believe
