Luke 12:1-3

Be aware of the hypocrisy of leaders. Everything that they say in private eventually is leaked to the public. 

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

we need to be as wise as a serpent but as gentle as a lamb basing our wisdom on the Word of God. If we ask for wisdom in our current situations He is faithful to provide it. as representatives of Christ we need to be transparent in all we do…the good, the bad and the downright ugly in our lives to the glory of how god can take the uglies and turn them for our good and the good of his body, the church.

It’s as easy as 1.2.3.

Leaven: 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. Faithlife Study Bible

Practicing hypocrisy is senseless because eventually all deeds—both good and evil—will be exposed.

Luke 12: 1,2,3 (NKJV)

12 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.

Matthew 10:26 (NKJV)

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