1 Thessalonians 5:17

Greek writers used the adverb translated "without ceasing" to describe a hacking cough. Paul did not expect his readers to be in prayer every minute but to continue praying frequently.

"Not surprisingly Paul wished his converts to be people of prayer. He himself was devoted to prayer as a fundamental activity in his life (cf. 1 Thessalonians 1:2 b; 2 Thessalonians 1:11; Romans 1:10; Colossians 1:3; Colossians 1:9). In several of his letters he instructs his readers to devote themselves to prayer (cf. 1 Thessalonians 5:25; 2 Thessalonians 3:1; Romans 12:12; Philippians 4:6; Colossians 4:2-3)." [Note: Wanamaker, p. 200.]

"If we live in this way, conscious continually of our dependence on God, conscious of His presence with us always, conscious of His will to bless, then our general spirit of prayerfulness will in the most natural way overflow into uttered prayer. It is instructive to read again and again in Paul’s letters the many prayers that he interjects. Prayer was as natural to Paul as breathing. At any time he was likely to break off his argument or to sum it up by some prayer of greater or less length. In the same way our lives can be lived in such an attitude of dependence on God that we will easily and naturally move into the words of prayer on all sorts of occasions, great and small, grave and gay. Prayer is to be constant." [Note: Morris, The First . . ., p. 173.]
