The Practice of the Apostles
by Scott D. Hendricks
I remember that St. Basil the Great solved the question how the Apostles could pray without ceasing, in this way: in everything they did, he replied, they thought of God and lived in constant devotion to Him. This spiritual state was their unceasing prayer.
