Every moment in life is a prayer, or could be. I think you can pray yourself into the mystery of the moment, or allow for the blessings of the moment to sustain you. Every moment is an invitation, and whatever you do in that moment, if it's dedicated to God, then it is a prayer.
Imagine what it would feel like, taste like, and smell like to believe you don't have to prove who you are by your accomplishments and labor...The culture we live under does not point you toward this deep truth. It instead has told you and reinforced the idea that you came into the world to be a machine, to accomplish, to labor, and to do. Nothing can be further from the truth and when you slowly begin to believe and understand your inherent worth, rest becomes possible in many ways.
