Luke 8:16-18

“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. So be careful how you listen; for whoever has [a teachable heart], to him more [understanding] will be given; and whoever does not have [a longing for truth], even what he thinks he has will be taken away from him.” [Matt 13:12; 25:29; Mark 4:25]
