Doxologies and Prayers
One of the characteristics of the letters of the New Testament are that many finish with short, pithy doxologies or prayers that summarise the main themes of the letter. The letters of Paul, Peter, Jude, and the writer to the Hebrews all contain this feature.
A detailed study of these verses uncovers the sweeping themes of whole letters: themes of election, salvation, sanctification, perseverance, equipping, restoration and eternal glory. Although small, these verses are like the eyepiece of a gigantic telescope that enables us to see the incredible size of God and his purposes for his people.
