Luke 8:16-17

“Now no one lights a lamp and then covers it with a container [to hide it], or puts it under a bed; instead, he puts it on a lampstand, so that those who come in may see the light. [Matt 5:15; Mark 4:21; Luke 11:33] For there is nothing hidden that will not become evident, nor anything secret that will not be known and come out into the open.
