Repent

Matthew 4:17

Repent, for the kingdom of heaven is near.

Revelation 12:11-12

They overcame him by the blood of the Lamb and by the word of their testimony.  they did not love their lives so much as to shrink from death

Therefore rejoice, you heavens and you who dwell in them!  But woe to the earth and the sea, because the devil has gone down to you!
He is filled with fury, because he knows that his time is short
 

Repent!
