Final answer:
Paul urged 'idlers' in Thessalonica to work and contribute, emphasizing that everyone should earn their living and support the community.
Step-by-step explanation:
In addressing the issue of 'idlers' in Thessalonica, Paul chose to urge them to work and contribute to their community. This is evident in the epistles he wrote to the Thessalonians, especially the Second Epistle to the Thessalonians, where he reminded them of the importance of working to earn their own living.
Paul's teaching here echoes the Christian principle that each person should contribute to the welfare of the community and not live off the work of others.
