The point of this Prayer Wall is not to register all the prayer going on, but to unite prayer, to inspire the growth of a praying community, and to therefore influence an increase in prayer across the city.
The Prayer Wall timetable details the hours across the week, and the 30 min slots that are various shades of pink are the time slots within which people are praying. Selecting these slots lets you know who is praying within these time slots and where they are from. From this information you can either link to that person to make contact, or link to the area they are from to connect with others praying within that area, and to connect with the prayer needs for that area.
The idea is that you select a time slot that you would like to pray within, register yourself against that time slot, and then get on with the praying. Thoughts on engagement and commitment are there to help with inspiration and direction. The guestbook and details of others praying are to facilitate connection and encouragement as part of a citywide praying community.
