If there is one thing St. Luke tries to teach Theophilus, and by extension us, it is the importance of prayer. From the prayers of praise and thanksgiving from Mary, Zechariah, and Simeon in his first two chapters, to the stress he makes that Jesus was Himself a man of prayer who sought His Father's aid during significant times in His ministry (check out chapters 3, 6, 9, and 22, among others), St. Luke's Gospel is filled with prayer.
