Passage
For whatsoever things you have spoken in darkness shall be published in the light: and that which you have spoken in the ear in the chambers shall be preached on the housetops.
For whatsoever things you have spoken in darkness shall be published in the light: and that which you have spoken in the ear in the chambers shall be preached on the housetops.
Luke 12:1 And when great multitudes stood about him, so that they trod one upon another, he began to say to his disciples: Beware ye of the leaven of the Pharisees, which is hypocrisy.
Luke 12:2 For there is nothing covered that shall not be revealed: nor hidden that shall not be known.
Luke 12:3 For whatsoever things you have spoken in darkness shall be published in the light: and that which you have spoken in the ear in the chambers shall be preached on the housetops.
Luke 12:4 And I say to you, my friends: Be not afraid of them who kill the body and after that have no more that they can do.
Luke 12:5 But I will shew you whom you shall fear: Fear ye him who, after he hath killed, hath power to cast into hell. Yea, I say to you: Fear him.
The verse centers on "light", "darkness", "whatsoever", "things", "spoken", "shall", and "published". It is saying that the contrast between light and darkness marks a real divide in how people respond to God's work.
The nearby context moves from verse 2's "For there is nothing covered that shall..." into verse 4's "And I say to you my friends...", so "light" and "darkness" 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 "light" and "darkness" with trust shaped by these words, not by a vague optimism outside the passage.
