WHAT IS THE FIRST SHOUT?  

Revelation 5:13 

“And every created thing which is in HEAVEN and ON THE EARTH and UNDER  THE EARTH and ON THE SEA, and all things IN THEM, I heard saying,

“To Him who sits on the throne, and to the Lamb, be blessing and honor and glory and dominion forever and ever.”

The Apostle John is standing in Heaven before God's Throne. He has been called up to see God's "End of the Age" plan of events. The Father holds up the Scroll which only Jesus is worthy to take and open. When Jesus takes the scroll all Heaven breaks loose in Praise. But the Praise does not stay in Heaven, it pours down onto the earth.  All of God’s Creation will join in with the SHOUT.  (You will be a part of this! You too will Shout!)

See Revelation chapters 4 and 5.

Every created thing and every person of God’s creation will SHOUT and give Glory and Honor and Praise to God and to Jesus Christ His Son, the Lamb of God.

The Apostle Paul seems to see this day when he writes to the Church at Philippi. 

"...so that at the name of Jesus every knee will bow,

 of those who are in heaven and on earth 

and under the earth,   

and that every tongue will confess that Jesus Christ is Lord,

 to the glory of God the Father." Philippians 2:10

Notice the same order from Heaven to earth to under the earth. And note that Paul sees "every tongue confessing." No exceptions, all creation, including all men, women, devils, angels must bow the knee and give God the Glory.

BUT WHEN WILL THIS HAPPEN???

      *The Old Testament Prophets also foresaw this 'End of days' Event. See all of Psalms 96* and Psalm 98. Also Isaiah 42:10-17; Isaiah 44:23; Isaiah 45:22-25, Isaiah 55:12, 1 Chronicles 16:31-33, Psalm 145:7-10, Psalm 69:34-36 and others....

“Let the heavens be glad, and let the earth rejoice;

Let the sea roar, and all it contains; 

Let the field exult, and all that is in it. 

Then all the trees of the forest will sing for joy

Before the Lord, for He is coming, 

For He is coming to judge the earth. 

He will judge the world in righteousness

And the peoples in His faithfulness.”

*Ps 96:11-13

The Shout will happen to prepare the World for the return of Jesus 

at the

 END OF THIS AGE

*SPOILER ALERT*

After Creation's "Shout" is done we hear further shouts like thunder coming from heaven.

With the breaking of each of the first 6 Seals come 6 more “SHOUTS” -but not like this first one.

As Jesus opens the first Four Seals the FOUR LIVING CREATURES  each Shout. See Revelation  6:1,3,5,7  - Seals #1-2-3-4

The 6th Shout comes up from the Martyred Saints under the Altar in Heaven. Revelation  6:10  - Seal #5

The 7th Shout comes from God Himself as He calls His Saints UP in the Rapture.  - Seal #6  - the sky opens up and all nations see Jesus coming down!

          ”For we say this to you by the word of the Lord, that we who are alive and remain until the coming of the Lord will not precede those who have fallen asleep.  For the Lord Himself will descend from heaven with a shout, with the voice of the archangel and with the trumpet of God, and the dead in Christ will rise first.  Then we who are alive, who remain, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord.”     1 Thessalonians 4:15-1

Immediately after the Creation's SHOUT, the first Shout, Jesus begins to OPEN THE Seals of the SCROLL which He has just received. He does this one Seal at a time. It is only after the seventh seal is opened that the scroll can be unrolled and the Wrath of God begun. 

The Seals are the events that 

"must take place" first. 

The timing for the opening of each successive Seal is in God's hands but may likely be in yearly increments*. 

*Except for Seals #6 and 7 opened on the same day at the end of Year #6. Seal #6 is the Rapture and Seal #7 introduces God's Wrath. There is no delay between these two events. "On the day Noah entered the Ark the Floods broke out." (Luke 17:22–27, cf.  The flood happened “on that very day Noah entered the ark” (Gen 7:13)  Jesus also gave this comparison: "On the same day Lot leaves Sodom the Fire falls." (see Luke 17:28–35) Jesus is illustrating that the day the church is taken up the wrath of God begins.
