Final answer:
No, not every chapter of 1 Thessalonians contains a reference to the Lord's return.
Step-by-step explanation:
No, not every chapter of 1 Thessalonians contains a reference to the Lord's return. In fact, the mention of the Lord's return is concentrated in three main sections of the book: 1 Thessalonians 1:9-10; 2:19-20; and 4:13-5:11. These sections focus on the eschatological hope of the early Christians and encourage believers to live in anticipation of Christ's return. The other chapters of 1 Thessalonians primarily deal with topics such as the author's relationship with the Thessalonian church, instructions for holy living, and pastoral advice.
