The leader of feats and our Saviour, the Lord Jesus Christ, before setting out on the feat of redeeming the human race, fortified Himself with a lengthy fast. And all ascetics, proceeding to work for the Lord, armed themselves by fasting and did not set out on the path of the Cross without the feat of fasting. They measured the very success of their ascetism by their success in fasting. -From the Teachings of St. Seraphim of Sarov
Moses fasted for many days. Awaken your minds, I entreat You, and lift them up at this opportune time, in company with Moses when he went up the mountain towards God. In this way may you start off afresh on your ascent, and be lifted up together with Christ, who did not merely go up a mountain but up to heaven, taking us with Him. Moses fasted for forty days on the mountain and according to the Scriptures he saw God, not darkly but face to face (Exod. 24:18). He talked to Him as someone would speak to his friend (Exod. 33:11, Deut. 34:10). –Saint Gregory Palamas
The church of Antioch fasted (Acts 13:2) and sent Paul and Barnabas off on their first missionary journey (Acts 13:3).
NOW there were in the church that was at Antioch certain prophets and teachers; as Barnabas, and Simeon that was called Niger, and Lucius of Cyrene, and Manaen, which had been brought up with Herod the tetrarch, and Saul. 2 As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them. 3 And when they had fasted and prayed, and laid their hands on them, they sent them away. Acts 13:1-3
Paul and Barnabas spent time in prayer and fasting for the appointment of elders in the churches (Acts 14:23).
Once St. Seraphim of Sarov was asked why the miracles of grace, so abundantly manifest in the past, were no longer apparent in his own day, and to this he replied: “Only one thing is lacking – a firm resolve”.
O gracious Jesus, our Physician and Helper in all miseries, strengthen us by the power of Your Holy Spirit that we may be able to adhere to Your saving precepts concerning fasting and prayer for the sake of our salvation and the salvation of our fellow men.
