Yeah, so you have still miserably failed to actually put it on a timeline. It doesn't seem as though you've even attempted to prove that verse 5 happens at a specific time. Because it mentions "the lamb that was slain" it must be talking about something occurring after the lake of fire, and by this same verse we also know that every single human that ever lived must certainly be conscious and must still exist?
What's missing from the context of Revelation 5:13 is the part where every creature in the universe is worshipping the Lamb of God Who takes away their sin, the sin of the world...and then suddenly Love Omnipotent pulls a lever & the lost are sucked down to some "hell" to be sadistically & pointlessly tortured before being endlessly obliterated out of existence by the unfeeling terminator machine whose short fuse & temper burst about the same time that His love expired like a carton of sour milk. Ditto for Phil.2:9-11; Isa.45:21-25; Col.1:20; Eph.1:10; John 1:29; 4:42; etc.
Do you know of a time before the lake of fire of Revelation 20 when the following occurs. If not before, then it must be fulfilled after people & angels are cast into the LOF.
This includes everyone in the universe, including the dead and demons:
Rev.5:13 And every creature which is in heaven, and on the earth, and under the earth, and such as are on the sea, and all that are in them, heard I saying, Blessing, and honour, and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever.
John speaks of "every creature" & to emphasize this again he repeats "and all that are in them":
Rev.5:13 And every creature which is in heaven, and on the earth, and under the earth, and such as are on the sea, and all that are in them, heard I saying, Blessing, and honour,
and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever.
This worship (v.13) uses the same worshipful words as the redeemed of vs 9-10 use in v.12:
12 Saying with a loud voice, Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing.
All this being in the context of salvation - "the Lamb that was slain" (v.12 & 13).
Does Revelation 5 say that everyone is saved? No.
Does it say that every creature on planet earth will praise God? Yes.
Does it say that birds and lizards will praise God? Pretty much.
If you can somehow twist your mind enough to use this verse to prove Universalism, you must also believe that God will "save" birds and lizards as well. Or else you must concede what it painfully obvious to everyone with a clear mind - that you don't have to be a saved Christian to praise God.
If you believe it refers to birds praising God, that's up to you. God spoke or prophesied through a donkey in the OT & Jesus said if these didn't praise the rocks would cry out (Lk.19:40).
In any case there are those creatures "under the earth", i.e. the wicked dead (e.g. Hitler) in their graves & demons in "hell" worshipping the Lamb. Which is a reference to the one who takes away the sin of the world (i.e. the cosmos, the universe, Jn.1:29).
The only other NT reference to "creature" in the context of salvation is this:
Js.1:17 Every good and perfect gift is from above, coming down from the Father of lights, who does not change like shifting shadows. 18 By his own choice, he gave us birth by the word of truth so that we would be a kind of firstfruits of his creatures.
Those believers at that time were just the firstfruits of the harvest of salvation "of his creatures".
Isa.45:
21 Tell ye, and bring
them near; yea, let them take counsel together: who hath declared this from ancient time?
who hath told it from that time?
have not I the LORD? and
there is no God else beside me; a just God and a Saviour;
there is none beside me.
22 Look unto me, and be ye saved, all the ends of the earth: for I
am God, and
there is none else.
23 I have sworn by myself, the word is gone out of my mouth
in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear.
Phil.2:9 For this reason also, God highly exalted Him, and bestowed on Him the name which is above every name,
10 so that at the name of Jesus EVERY KNEE WILL BOW, of those who are in heaven and on earth and under the earth,
11 and that every tongue will confess that Jesus Christ is Lord, to the glory of God the Father.
"You forget that evangelicals claim that God is omnipotent, infinitely patient, and all-wise, but upon further consideration they actually believe God lacks all 3 qualities. Once people reject Him in this life, God doesn't know how to give them another chance after death. Why not? Because He is just not resourceful enough to give them this new opportunity. You see, Clement, when Jesus preaches to the wicked "spirits -in "prison" (= Hell--1 Peter 3:19; 4:6), Jesus never considered the possibility that some of them might respond, and so, He forgot to give the altar call! And when, Christ anticipates every knee on earth, in heaven, and in Hell bowing after death and confessing Him as Lord, He's sorta stuck with all those lost souls in heaven {Philippians 2:9-11). What Paul doesn't tell you here is that there is a trap door under all these lost souls. So after Jesus gets the worship and confession of His Lordship, He sneakily pulls the lever and all those lost souls fall screaming back to Hell."
1 Timothy 2:4 + God does all He desires = all will be saved?
