Paul had previously visited Thessalonica, but his stay was cut short (see Acts 17:1-9). His letter sought to addresses those things that he had not previously spoken about, but were very much needed.
One of Paul’s concerns was that those who had recently come to faith, and discovered their place of belonging within the church, were not receiving enough support to learn more and grow into a deeper life with Christ.
Paul’s approach in each of the main sections of the letter is given a key emphasis on hope (1:3 thanksgiving & hope; 2:19 nurture & hope; the coming of the Lord & hope).
When “Church Rebooted” is responded to fully, it will teach the world!
