The Parable of the Revealed Light
Luke 8:16-18

16 “No one, when he has lit a lamp, covers it with a vessel or puts it under a bed, but sets it on a lampstand, that those who enter may see the light. 17 For nothing is secret that will not be revealed, nor anything hidden that will not be known and come to light. 18 Therefore take heed how you hear. For whoever has, to him more will be given; and whoever does not have, even what he seems to have will be taken from him.”
