‘No one lights a lamp to cover it with a bowl or to put it under a bed. No, it is put on a lamp-stand so that people may see the light when they come in. For nothing is hidden but it will be made clear, nothing secret but it will be made known and brought to light. So take care how you listen; anyone who has, will be given more; anyone who has not, will be deprived even of what he thinks he has.’
