WHEN
Paul wrote, in his first letter to the Thessalonians, "Pray without ceasing," and prefaced this admonition with the words, "Rejoice evermore," following it with, "In every thing give thanks," one can readily see that the writer of this epistle recognized joy and gratitude as essential to true prayer, and these two qualities are so linked together as to make it difficult to find where the one ends, and the other begins, in attempting to differentiate.
