1 Thessalonians 3:2
And sent Timotheus, our brother, and minister of God, and our fellowlabourer in the gospel of Christ, to establish you, and to comfort you concerning your faith: And sent Timotheus, our brother, and minister of God, and our fellowlabourer in the gospel of Christ, to establish you, and to comfort you concerning your faith:
Timothy was sent to the Thessalonians to establish them and to comfort them concerning their faith. His mission was one of strengthening and encouraging them in what they believed. The report he brought back to Paul from Macedonia was that they had remained faithful to God. Despite trial and hardship they were still holding fast to faith and love.
