Worshiping the Lamb

"And I heard every creature in heaven and on earth and under the earth and in the sea, and all that is in them, saying, 'To him who sits on the throne and to the Lamb be blessing and honor and glory and might forever!'"--Rev 5:13

If you've read the account of Revelation 4 and 5, you know that 4 contains an account of the elders and angels in heaven bowing down before the throne of God to worship him.  They sing "Holy, holy, holy", and night and day "they never cease"(4:8).  This is a clear reminder of Isaiah 6, where the angels were singing the same song to God enthroned, even hundreds of years earlier.
But notice that there in 5:13, whereas God is worshiped by the angels and elders, the Lamb of God, Jesus the Christ, is not just worshiped by the angels and elders as His Father is.  He's worshiped by "EVERY creature in heaven and on earth and under the earth."  The point isn't that Jesus deserves more worship than God the Father--the point is that in order to approach the throne of God, man must have a Mediator (1 Tim. 2:5, Heb. 4:15-16).  Since this is the case, for man himself to be able to worship God on His throne, He must worship the Lamb of God, the Christ, as the Mediator between God and man.  This is why the New Testament has such a clear message about Jesus' Lordship and Authority--man in His fallen state MUST have a Mediator if he'll approach God.  Therefore, man doesn't have God unless He has Christ (1 Jn. 2:23, 2 Jn. 6), nor does He have Christ unless he has God (Jn. 6:44,65).  But having Christ as his Mediator, he can approach the throne of grace and worship with the angels and elders in heaven.

This is why belief in God is so hard in our time today--people have no problem believing that the world has problems and that "things aren't the way they're supposed to be", but they struggle with the fact that THEY THEMSELVES are part of the problem too, and thus will never get to the place of accepting that they need a Mediator between themselves and God.  But the truth is that you can't know, see, or have God unless you HAVE this Mediator.  And He went to the torture of the cross to give Himself as the Mediator.  Because of this, those who humble themselves can approach the throne of God and sing "To him who sits on the throne and to the Lamb be blessing and honor and glory and might forever!".  They don't sing this just because they're commanded to worship (as though worship is just an act of obedience)--they sing it because they WANT to worship, because worship is a response to recognizing and understanding God's worth-ship.

Understanding their fallen state, they treasure the work of Christ who went to the cross for them, so that he would sit on the throne for them.  He "always makes intercession for them" before Holy God (Mk. 16:19, Heb. 7:25, 1 Jn. 2:2).  And they love Him for it.
