8:16 “No one lights 1 a lamp 2 and then covers it with a jar or puts it under a bed, but puts it on a lampstand so that those who come in can see the light. 3 8:17 For nothing is hidden 4 that will not be revealed, 5 and nothing concealed that will not be made known and brought to light. 8:18 So listen carefully, 6 for whoever has will be given more, but 7 whoever does not have, even what he thinks he has 8 will be taken from him.”
[8:17] 4 sn Nothing is hidden. Light also exposes, and Jesus was suggesting that his teaching likewise revealed where people are and where they will be. Truth will be manifest in the future, just as it was declared by him then. Nothing will be concealed.
[8:18] 8 sn The phrase what he thinks he has is important, because it is not what a person thinks he has that is important but whether he actually has something or not. Jesus describes the person who does not heed his word as having nothing. The person who has nothing loses even that which he thought was something but was not. In other words, he has absolutely nothing at all. Jesus’ teaching must be taken seriously.
