Revelation 4-11: Worthy is the Lamb

After hearing the messages for the churches, John is called up into heaven to see what will take place at the end of time.  First he sees the throne of God and the living creatures crying 'Holy, holy, holy,' while the twenty-four elders lay down their golden crowns and confess,
 “You are worthy, our Lord and God,
   to receive glory and honor and power,
for you created all things,
   and by your will they were created
   and have their being.” - Rev 4:11 NIV
John then weeps, when he sees the scroll that cannot be opened, until he is told by one of the elders, “Do not weep! See, the Lion of the tribe of Judah, the Root of David, has triumphed. He is able to open the scroll and its seven seals.” - Rev 5:5 NIV

Then the lamb, the only one who is worthy, opens the seven seals and sets into motion the end of time.  There is silence after the seventh seal is opened and then the seven angels sound their trumpets and disaster falls upon the earth:  a third of the earth is destroyed by hail and fire, a third of the sea is turned to blood, a third of the rivers and springs turn bitter, a third of the sun, moon and stars turn dark, locusts with the power of scorpions are given the power to torture any without the seal of God on their foreheads, and a mighty army is released to kill a third of mankind.   Woe upon woe falls upon the earth.

John sees, but is told not to write about the events that occur when the seventh angel sounds his trumpet, But in the days when the seventh angel is about to sound his trumpet, the mystery of God will be accomplished, just as he announced to his servants the prophets.” - Rev. 10:7 NIV

Whatever John saw, this mystery of God, will ultimately bring about the kingdom of God.  The seventh trumpet is sounded and there were loud voices in heaven, which said:
   “The kingdom of the world has become the kingdom of our Lord and of his Christ,
   and he will reign for ever and ever.”
And the twenty-four elders, who were seated on their thrones before God, fell on their faces and worshiped God, saying:
   “We give thanks to you, Lord God Almighty,
   the One who is and who was,
because you have taken your great power
   and have begun to reign. - Rev. 11:15-17 NIV

The kingdom of this world has now become the kingdom of our Lord and of his Christ.  The sacrificial lamb, the only one who has ever been worthy,  now rules with God the Father.
