Who was the author? Like 1 Thessalonians, 2 Thessalonians was written by the Divinely-inspired apostle Paul.
What is the book? Second Thessalonians is essentially a follow-up letter to the believers in Thessalonica, the capital city of the Roman province of Macedonia.
Where was it written? The letter was written by Paul while he stayed in Corinth, his major stop after leaving Thessalonica.
When was it written? Paul probably wrote the letter not long after 1 Thessalonians, maybe one to six months, putting the date of the second letter around summertime of A.D. 50.
Why? Either a letter or verbal report from Thessalonica after the delivery of the first letter seems to have prompted Paul to write again perhaps to clarify some of content of the first letter, seemingly to address a forged letter that had circulated, and to otherwise admonish and exhort the believers there on matters related to the Lord's return.
How? With remarkable Spirit-given tact, 2 Thessalonians tries to suppress at least a little the hysterical excitement of the people without completely extinguishing the hope that should in fact change how Christians live. Paul understood how fear and faith are needed as we live in this in-between time waiting and watching for the Lord's return.
