Luke 12:1–3

Corrupt deeds hidden will always be revealed!

Beware of the hypocrisy and lies of those who are motivated by their need for power and control.

Let This Be Our Prayer For The World...
Let the rain come and wash away
the ancient grudges, the bitter hatreds
held and nurtured over generations.
Let the rain wash away the memory
of the hurt, the neglect.
Then let the sun come out and
fill the sky with rainbows.
Let the warmth of the sun heal us
wherever we are broken.
Let it burn away the fog so that
we can see each other clearly.
So that we can see beyond labels,
beyond accents, gender or skin color.
Let the warmth and brightness
of the sun melt our selfishness.
So that we can share the joys and
feel the sorrows of our neighbors.
And let the light of the sun
be so strong that we will see all
people as our neighbors.
Let the earth, nourished by rain,
bring forth flowers
to surround us with beauty.
And let the mountains teach our hearts
to reach upward to heaven.
Amen.
Rabbi Harold Kushner

Luke 12:1–3

1 In the meantime, when an innumerable multitude of people had gathered together, so that they trampled one another, He began to say to His disciples first of all, “Beware of the leaven of the Pharisees, which is hypocrisy. 2 For there is nothing covered that will not be revealed, nor hidden that will not be known. 3 Therefore whatever you have spoken in the dark will be heard in the light, and what you have spoken in the ear in inner rooms will be proclaimed on the housetops. The New King James Version

The Greek word used here refers to fermented dough that was mixed in with new dough and used as a rising agent. The small amount used in baking would permeate the entire batch of new dough. Leaven serves as an apt metaphor to describe the widespread effects of the Pharisees’ hypocritical teachings and actions. 

Jesus seems to be referring to the Pharisees’ hidden sins, which will be exposed at the final judgment. Faithlife Study Bible

Leaven here represents the presence of corruption. Unleavened bread is what the Jews ate at Passover. The corruption in view here is hypocrisy. Practicing hypocrisy is senseless because eventually all deeds—both good and evil—will be exposed. 

All secrets will be revealed by God. The inner room was a storeroom which was surrounded by other rooms; it was the most private part of a house. The NKJV Study Bible 

Matthew 10:26 Therefore do not fear them. For there is nothing covered that will not be revealed, and hidden that will not be known.

Matthew 16:6 Then Jesus said to them, “Take heed and beware of the leaven of the Pharisees and the Sadducees.”

Mark 4:22 For there is nothing hidden which will not be revealed, nor has anything been kept secret but that it should come to light.

Mark 8:15 Then He charged them, saying, “Take heed, beware of the leaven of the Pharisees and the leaven of Herod.”

Luke 8:17 For nothing is secret that will not be revealed, nor anything hidden that will not be known and come to light.
