Mike Aquilina over at the way of the Fathers has three posts for Lent. His first one is on prayer.
How do you know it’s Lent?
It’s not so much by the ash mark on your forehead or fish marks on the calendar. Tradition tells us that Lent has three distinguishing marks: prayer, fasting and almsgiving.
Prayer is a conversation that never ends. In the Scriptures, St. Paul says: “Pray at all times” (Eph 6:18); “Pray without ceasing” (1 Thess 5:1); and “be constant in prayer” (Rom 12:12). He saw prayer as endless conversation.
