Luke 12:3

Luke 12:3 Meaning and Commentary

Luke 12:3

Therefore whatsoever ye have spoken in darkness
In the most private manner, to one another:

shall be heard in the light;
which makes all things manifest, the day shall declare it:

and that which ye have spoken in the ear in closets;
whispered to persons in their bedchambers, and places of the most secret retirement;

shall be proclaimed upon the housetops;
declared in the most public manner: in ( Matthew 10:27 ) these words are so expressed, as to carry in them such a sense as this; that what was told the disciples by Christ, in the most private place and way, should be published by them, in the most free and open manner; (See Gill on Matthew 10:27).

Luke 12:3 In-Context

1 By this time the crowd, unwieldy and stepping on each other's toes, numbered into the thousands. But Jesus' primary concern was his disciples. He said to them, "Watch yourselves carefully so you don't get contaminated with Pharisee yeast, Pharisee phoniness.
2 You can't keep your true self hidden forever; before long you'll be exposed. You can't hide behind a religious mask forever; sooner or later the mask will slip and your true face will be known.
3 You can't whisper one thing in private and preach the opposite in public; the day's coming when those whispers will be repeated all over town.
4 "I'm speaking to you as dear friends. Don't be bluffed into silence or insincerity by the threats of religious bullies. True, they can kill you, but then what can they do? There's nothing they can do to your soul, your core being.
5 Save your fear for God, who holds your entire life - body and soul - in his hands.
