Why fast at Lent?
Lord, my deepest hunger is for you...May you alone be my food, my sustenance; keep me hungry for you... James Howell
I tend to take the Lenten sacrifice as a prompt to prayer: It should be something that one does habitually so that when the urge to do XXX comes about, it serves as a reminder to pray at that moment. For those who don't pray, it can simply be a call to mindfulness and awareness of the automaticity of life.
