“you whitewashed wall!”

Acts 23:3
Yo, Paul just went in on them!  He is admonishing the Pharisees and Sadducees by calling them whitewashed walls.  The meaning is they look pure, and good on the outside, but inside there is nothing good.  Tombs were washed white back then, so they looked nice but inside was death and decay.  Examine yourself today.  Allow Jesus to clean out all the filth that lays under the exterior.  Give Him your heart.  He will renew you, and give life.
