The message has been addressed to the Saints but we also see a messege now addressed to all of creation. "And every creature which is in heaven, and on the earth, and under the earth, and such as are in the sea, and all that are in them," verse 13. The redemption that is about to be consumated by the Lamb, includes not only man, but every creature. That ties in with Romans 8:22, "For we know that the whole creation groaneth and travaileth in pain together until now."
The whole of creation was cursed because of Adam's sin. We read about that curse in Genesis 3:14- 19. The problem of the environment is the problem of sin. It is right and good that man should care for the earth as God had commanded him, but the creation willnot be restored until Christ lifts the curse God placed on the earth. That day will surely come, we read about it in Isaiah 11.
All of creation will join in the praise of God and of the Lamb. In Colossians 1:16, we learn that all things were created by Him and for Him. We now see all of creation praising Him. It is an awesome thought to realize that everything that was created, was created to glorify God. Only fallen man dishonors God instead of glorifying Him. That situation will be reversed in the lives of some. Those who refuse to glorify God will be dismissed from His presence forever.( John 3:36)
If you are not a believer, this is the issue of your life.
Notice the duration of this glorifing of God, "For ever and ever." If you do not delight to praise God now, heaven is not the place for you.
Now in verse 14, the Church and the Cherubim, bow down before the Lamb and worship Him. There is an application here for our lives. Our lives ought to be a preview of that soon coming day, our hours and our days ought to be filled with worship and praise to the Lord. We have a description of that worship in Ephesians 5:19.
In the Church, our worship service ought to be a very special hour in the week. Singing God"s praises, bringing our gifts, quietly praying and meditating and carefully listening to God's word.
That will be our eternal occupation, worship is a private act and worship is also a corporate act, we see this in the assembled church worshipping in heaven.
If you do not assemble and worship with the body of Christ now, what makes you think you will be invited to do so in heaven?
