St. John of the Cross says: “The person who flees prayer is fleeing everything that is good.” Without air to our lungs it is just a matter of minutes that we will suffocate and die; what air is to the lungs, prayer is to the soul. St. Paul exhorts us: “Pray without ceasing” (I Thes. 5:17). To the Ephesians ha says “Pray at all times.” (Eph. 6:18). In the Garden of Olives Jesus earnestly warned the Apostles to pray: “Watch and pray”. (Mt. 26:41). Because they failed to pray the Apostles failed Jesus when He most desperately needed their company and their friendship.
There is an obvious connection to lack of prayer and succumbing to sin. The more and better we pray, the more graces we receive from God and the more power we have in our will to resist the imperious demands of the flesh, the insistent attacks of the devil and the astute and ever-present seductions of the world that surrounds us with its glamour and allurements.
