One thing I have noticed about Doctrine. When one's Doctrine is correct it continually lines up with the word of God it's like a basket weave. It's all interconnected and it builds upon itself. So I find it interesting in the following verses in rev 5;
9 And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation;
10 And hast made us unto our God kings and priests: and we shall reign on the earth.
That is great support for the pretrib rapture. Here we have redeemed Saints in heaven before the seals are even broken open.
That is the pre-trib Rapture right there,because they are in heaven and they're singing that song that they've been redeemed from the Earth.
Ahem...BEFORE THE TRIB.
