God doesn’t want you either, and he certainly hasn’t laid up any treasure for you, but neither will he turn you away. That’s the consolation in serving himno matter how bad the service, it won’t be spurnedbut you aren’t told how to do it.
If you have layers, if the lower layers are calciferous grottoes, then you have to follow the water as it moves or you’ll upset the whole structure.
