When we pray, it's the Holy Spirit Who makes the divine presence real to our spirits, and then we seem to 'feel close' to a living God. We are spiritually overwhelmed by divine glory.
During those days when you're exhausted and during those days when you're frustrated, during those days when you're being attacked by your own people for doing what you think is right, remember you're part of a progression that goes back a long time of ordinary people who are doing their best to make it a better world.
