Is This What Heaven Is Like?

Some of you might not know this, but when I first became a Christian I loved music to the extent where I would describe worship as music and singing.  I may get made fun of for this, but I was like what is shown in this video that when 'worshipping' I would lift my hands.  Obviously, I have changed, my views on the subject have changed.  But my question is this, if you participate in music and singing like this, and I am not necessarily criticizing the raising of hands nor am I criticizing the lyrics to the song, but I want to ask you if you think you will be doing this (singing these types of songs with the same or similar music) when you are 70 or is this just a fad?  Or is this something you do because it feels good and puts you in a heightened emotionalized state?  I guess another question I am trying to ask is why is everyone, from what I can tell, in this video and typically what you see in most places which have such music (e.g. Passion concerts, Kari Jobe concerts, etc.) so young?  Why are most of these people college age and younger (Please remember that I am not too far removed as I am only 27 years old)?  Does this kind of music and concerts unite the body or divide it?  And on top of that, will this be what heaven is like? 

Finally, what is worship?  Is worship only singing?  It seems not.  The Bible is clear with examples from Scripture.  Abraham worshiped by offering sacrifices, so did Israel (e.g. the tent and tabernacle, the temple).  Praise the Lord, this was fulfilled in Jesus Christ.  For Hebrews 9-10 helps us in this talking about the fact that Christ's death fulfilled all that the many many sacrifices couldn't 'forgiveness of sins' and 'cleansing of our guilt by His blood' of which it then says in chapter 10:

Therefore, brethren, since we have confidence to enter the holy place by the blood of Jesus, by a new and living way which He inaugurated for us through the veil, that is, His flesh, and since we have a great priest over the house of God, let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled clean from an evil conscience and our bodies washed with pure water. Let us hold fast the confession of our hope without wavering, for He who promised is faithful; and let us consider how to stimulate one another to love and good deeds,not forsaking our own assembling together, as is the habit of some, but encouraging one another; and all the mre as you see the day drawing near. 

Of which it means that because of Christ's blood shed we no longer need a high priest to enter a temple, into the Holy of Holies once a year.  The curtain/veil of that temple was torn down of which by His blood He has earned for us or gained for us entrance into the Holy of Holies (the very presence of God Himself)!  And this God is Holy, Holy, Holy (Isaiah 6), and in heaven this is the picture:

Behold, a throne was standing in heaven, and One sitting on the throne. And He who was sitting was like a jasper stone and a sardius in appearance; and there was a rainbow around the throne, like an emerald in appearance. Around the throne were twenty-four thrones; and upon the thrones I saw twenty-four elders sitting, clothed in white garments, and golden crowns on their heads. Out from the throne come flashes of lightning and sounds and peals of thunder And there were seven lamps of fire burning before the throne, which are the seven Spirits of God; and before the throne there was something like a sea of glass, like crystal; and in the center and around the throne, four living creatures full of eyes in front and behind. The first creature was like a lion, and the second creature like a calf, and the third creature had a face like that of a man, and the fourth creature was like a flying eagle. And the four living creatures, each one of them having six wings, are full of eyes around and within; and day and night they do not cease to say, "HOLY, HOLY, HOLY is THE LORD GOD, THE ALMIGHTY, WHO WAS AND WHO IS AND WHO IS TO COME." And when the living creatures give glory and honor and thanks to Him who sits on the throne, to Him who lives forever and ever, the twenty-four elders will fall down before Him who sits on the throne, and will worship Him who lives forever and ever, and will cast their crowns before the throne, saying, "Worthy are You, our Lord and our God, to receive glory and honor and power; for You created all things, and because of Your will they existed, and were created."

Is worship just music and singing?  No.  But the command to worship our Lord comes clearly, in its method, in Hebrews 12: 

"Therefore, since we receive a kingdom which cannot be shaken, let us show gratitude, by which we may offer to God acceptable worship with reverence and awe; for our God is a consuming fire."

And John 4:

"But an hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for such people the Father seeks to be His worshipers. God is spirit, and those who worship Him must worship in spirit and truth." 

We are to worship our God in truth.  Most Definitely we are to worship Him according to His commands only, those commands found in Scripture only (Deuteronomy 12:32).  Who else is better to tell us how to worship God than God Himself.  And finally, we are to worship Him in spirit.  Which means not the Holy Spirit, although the Holy Spirit is in our hearts to strengthen and enable us to worship God, but our own personal spirit meaning our hearts.  How do I know this?  Ephesians 5:19, our Lord where, through the Apostle Paul, He calls us as part of our worship to speak Psalms, hymns, and spiritual songs, He clarifies that statement by saying, "singing and making melody in your heart to the Lord."  If you learn anything from this post, learn this: our worship is in spirit and truth.  God does not want your beautiful voice, your hands raised, your heightened emotions unless He has your heart.  That's why in Hosea 6:6 our Lord says, "For I desire steadfast love (heart) and not sacrifice (external), the knowledge of God rather than burnt offerings."
