2:9-10
9: For you remember, brothers, our labor and toil: we worked night and day, that we might not be a burden to any of you, while we proclaimed to you the gospel of God.
Paul reminds them of his time with them. We know from studying Paul that he was a tent maker and would do that in order to pay for travels and needs. That way he didn’t need to depend on others to sustain his mission trips, but could focus on presenting the Gospel rather than raising funds. Paul also notes in this verse that they proclaimed the Gospel to the Thessalonians as they worked.
10: You are witnesses, and God also, how holy and righteous and blameless was our conduct toward you believers.
Paul’s conduct while with the believers was worthy of repetition. He and Silas treated the Thessalonians well and were seen as respectable.
We should seek to live in unity with others, whenever possible. There are cases, however, where we must stand our ground and speak of what is right. Paul and Silas’ testimony among the Thessalonians was without reproach. They were in unity with the believers, but were chased out by the Jews who didn’t want the Gospel preached. We should seek to live our lives without reproach. Paul and Silas were not chased out because of bad conduct, but were chased out because the Jews didn’t want to hear the truth of the Gospel. Our reputation should be without reproach and our words should be words of truth.
