Praying to change the world

Dr B has written from Leipzig about the Monday evening prayers which helped trigger the peaceful revolution in the GDR and which still continue today.
I found it very moving to think of the small group of people meeting week in, week out. That this small act of prayerful resistance becomes the act that inspires others across the land to do the same and sets the tone for the peaceful revolution.
Speaks to me of the discipline of piety having transformative power.
