1. The primary focus of The Thessalonians Epistles is Christian living in light of eternity.
2. The "bookends" of 1TH 1:3 and 1TH 5:8 reveal the book's theme- the well balanced Christian life.
3. The key verse of 1TH 2:13 shows that God's Word works through faith.
4. As we learn in 1TH 3:6 and GAL 5:6, faith only works through love (i.e. The Spirit).
5. Where faith is animated by love, there is always hope. See COL 1:4-5
6. This epistle is closely related in content to the Old Testament book of Ruth, which provides a perfect Biblical illustration of the practical truths of this book.
7. The historical background to the epistle is found in ACT 16:9-10 through ACT 17:1-9. The epistle was written A.D. 50/51.
Whereas Ephesians is the epistle of Trinitarian doctrine, 1 Thessalonians is the epistle of the three fold strand of Christian living: faith, love and hope. (1TH 1:3, 1TH 5:8cf. 1CO 13:13 and COL 1:4) These three spiritual virtues cover every need of the Christian life: faith looks upward, love looks around, and hope looks forward. Also, faith comes from Christ, love from The Spirit, and hope from The Father.
"A three fold chord is not easily broken."-ECC 4:12
