1 Thessalonians was a heartwarming letter from the apostle Paul to an infant church at Thessalonica. Even though the church was young in the faith, it was exemplary, demonstrating the reality of their election in faith, love, and obedience to the spread of the gospel of Christ. The second coming of Christ is mentioned repeatedly throughout this heartwarming letter. It conveys a glorious message of hope.
After Paul's first letter to the church at Thessalonica false teaching about the second coming of Christ had caused the faith of some to waver. 2 Thessalonians was written primarily to correct erroneous doctrine, and encourage the believers to look forward to the day when the Lord will make all things right. He also has a word about idleness.
