Passage
For there is nothing covered, that shall not be revealed; neither hid, that shall not be known.
For there is nothing covered, that shall not be revealed; neither hid, that shall not be known.
Luke 12:1 In the mean time, when there were gathered together an innumerable multitude of people, insomuch that they trode one upon another, he began to say unto his disciples first of all, Beware ye of the leaven of the Pharisees, which is hypocrisy.
Luke 12:2 For there is nothing covered, that shall not be revealed; neither hid, that shall not be known.
Luke 12:3 Therefore whatsoever ye have spoken in darkness shall be heard in the light; and that which ye have spoken in the ear in closets shall be proclaimed upon the housetops.
Luke 12:4 And I say unto you my friends, Be not afraid of them that kill the body, and after that have no more that they can do.
The verse centers on "nothing", "covered", "shall", "revealed", "neither", and "known". It is saying that the verse draws attention to "nothing" and "covered", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "In the mean time when there were..." into verse 3's "Therefore whatsoever ye have spoken in darkness...", so "nothing" and "covered" belong inside that flow. In Luke context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "nothing" and "covered" with trust shaped by these words, not by a vague optimism outside the passage.
