Waiting is hard. You only have to look at husbands waiting for their wives outside the shops! Some of the believers at Thessalonica were also having trouble waiting for Jesus to return as he promised. In 2 Thessalonians 3:6-18 we find that some of them had adopted a passive attitude to the extent that they no longer worked with their hands and were relying on the generosity of others to live. Paul would have none of this. He urged the believers at Thessalonica to live with a sense of the balance, purpose and discipline. The fact that Jesus is coming does not give us an excuse to put our feet up but instead get busy with the work of the gospel.
