The Need for Repentance

Luke 13:1-5

Now there were some present at that very season who told him of the Galilæans, whose blood Pilate had mingled with their sacrifices.

And he answered and said unto them, Think ye that these Galilæans were sinners above all the Galilæans, because they have suffered these things?

I tell you, Nay: but, except ye repent, ye shall all in like manner perish.

Or those eighteen, upon whom the tower in Siloam fell, and killed them, think ye that they were offenders above all the men that dwell in Jerusalem?

I tell you, Nay: but, except ye repent, ye shall all likewise perish.
