It is not unlikely Satan knows when Jesus returns to create his peace. Scripture gives many indications about this.
By David Wilkerson
"But the earth and the sea! For the devil has come down to you in great anger because he knows that he has only a little time." (Rev 12:12)
Jesus himself does not know the exact time he comes to bring the bride. But we must know the time.
Room. 13. 11 And we must do this, as we know the time that the hour has come when we shall wake up from sleep; For salvation is closer to us than when we came to faith. 12 It suffers with the night, and sometimes by day; Therefore let us take the deeds of darkness, but put on the weapons of light!
It darkens in this world, but shines for the church of God! It will also darken first before Israel, before the light also rises to them and they are saved as a man in one day! What a wonderful future for those who belong to the God of Israel!
