Luke 8:16-17; Luke 11:33-36; Luke 6:47-49

16 "No one lights a lamp and hides it in a jar or puts it under a bed. Instead, he puts it on a stand, so that those who come in can see the light. 17 For there is nothing hidden that will not be disclosed, and nothing concealed that will not be known or brought out into the open.
33 "No one lights a lamp and puts it in a place where it will be hidden, or under a bowl. Instead he puts it on its stand, so that those who come in may see the light. 34 Your eye is the lamp of your body. When your eyes are good, your whole body also is full of light. But when they are bad, your body also is full of darkness. 35 See to it, then, that the light within you is not darkness. 36 Therefore, if your whole body is full of light, and no part of it dark, it will be completely lighted, as when the light of a lamp shines on you."
47 I will show you what he is like who comes to me and hears my words and puts them into practice. 48 He is like a man building a house, who dug down deep and laid the foundation on rock. When a flood came, the torrent struck that house but could not shake it, because it was well built. 49 But the one who hears my words and does not put them into practice is like a man who built a house on the ground without a foundation. The moment the torrent struck that house, it collapsed and its destruction was complete."
