If it applied only to monks, the Apostle Paul would not have written to the Christians in Thessalonica “to pray without ceasing” (I Thessalonians 5:17).
The Apostle repeats the Lord’s command, word for word, and issues it to all Christians without distinction, whether monks or laymen.
St. Gregory Palamas lived a life of asceticism for some time as a young hieromonk in a monastery in Beroea. The elder Job, a well-known ascetic whom everyone respected, lived in that monastery. It happened that, in elder Job’s presence, St. Gregory quoted the Apostle’s words, asserting that ceaseless prayer is the obligation of every Christian and not just for monks.
However, elder Job replied that ceaseless prayer is the obligation of the monk only, and not for every Christian. Gregory, as the younger of the two, yielded and withdrew in silence. When Job returned to his cell and stood at prayer, an angel in great heavenly glory appeared to him and said: “O Elder, do not doubt the truthfulness of Gregory’s words; he spoke correctly and you should think likewise and pass it on to others.”
Thus, both the Apostle and the angel confirmed the commandment that all Christians must pray to God without ceasing.
Not only without ceasing in church, but also without ceasing in every place and at all times, and especially in your heart.
For if God does not for a moment tire of giving us good things, how can we tire of thanking Him for these good things?
