“pray without ceasing;”
We have a form of ascesis called prayer of the heart. It is the unceasing repitition of a certain prayer throughout the day, an unceasing prayer:
“Lord Jesus Christ, Son of God, have mercy on me, a sinner.”
It takes a little practice, but after awhile it becomes as easy and regular as breathing. It becomes the background mantra of your life.
Kolokotronis,
Absolutely a wonderful prayer. I believe in staying close to the cross to confess sin.
There are many others, such as the admonition to pray about everything.
“Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.” Philippians 4:6
