The battle of prayer

"Be sober and vigilant. Your opponent the devil is prowling around like a roaring lion looking for [someone] to devour. Resist him, steadfast in faith, knowing that your fellow believers throughout the world undergo the same sufferings." (1 Peter 5: 8 – 9)

The Catechism of the Catholic Church has this to say on prayer:

"Prayer is a gift of grace but it always presupposes a determined response on your part because those who pray "battle" against themselves, their surroundings, and especially the Tempter who does all he can to turn them away from prayer. The battle of prayer is inseparable from progress in the spiritual life. We pray as we live because we live as we pray."

"Saint Michael the Archangel, defend us in battle, be our protection against the malice and snares of the devil. May God rebuke him we humbly pray; and do thou, O Prince of the Heavenly host, by the power of God, thrust into hell Satan and all evil spirits who wander through the world for the ruin of souls. Amen."
