Hello Sandpiper;
Thank you for sharing the All-City Prayer meeting.
20 years ago I showed up to Wednesday evening service and nobody was there. If felt strange so I put on my guitar and gave thanks to the Lord for He is good, and started playing.
As I went into the first song, an elderly member came in, then another and another. It was one of the best worship services I ever attended. It can start with 1 person, one family, one community, one church, one city and one nation.
I agree that a day of prayer can be the beginning of revival in one small town, city, state allowing the Spirit to move to the next church, town and city.
His love endures forever.
God bless you always, and your family.
