Paul’s tone to the Thessalonian church is very different than the Galatian church. Where the Galatian church was struggling to hold their young faith in the face of false teachers, the Thessalonian church were exemplary. So much so that the spoken Gospel was almost unnecessary, as the Thessalonian church's reputation did its own preaching. What a great compliment. There are probably a lot of ministers in the world today who which they had churches like this, it must be a joy to live in a community so devoted to the cause of Christ.
