In this covenant, God undertakes to maintain creation for us. Everything needs maintenance. Every machine works as long as it receives its occasional oil change. If its filter is not taken out, and cleaned or replaced, any mechanism will clog and stop working. Everything needs to be exposed to daylight or to receive the caustic of public truth. But the poor old British – no home truths have been told them for such a long time. Everything needs a service. And every church service is that service. Christian worship tells us what is missing, and supplies it to us, so that the Church can provide the maintenance that the nation requires.
