This is perhaps Paul’s most affectionate letter. He writes as a loving, gentle, and caring father, who is seeking to support and nurture the young church in Thessalonica.
The central theme of Paul’s letter is to encourage this church (and by extension, all followers of Jesus) to stand firm in their faith in the midst of opposition and to continue to grow towards spiritual maturity, that is to pursue a deeper understanding of God and one’s relationship to him.
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 1,000-page website ABibleADay.com to encourage people to explore the Bible. His main blog and many books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
