I am an exponent of Systematic Biblical Theology so I have the whole body of material covering all the Books of the Bible at my disposal and have acquainted myself with much that pertains to the Book of Revelation. I make a point of asking the Holy Spirit for guidance in all that I study and discuss, and the Spirit has led me to understand that some of the things of God are beyond human comprehension.
The Seven Sealed Scroll has been opened. John saw it opened and wrote about what he saw which is what God intended for him to do so that we could know what lies ahead. In one sense the Book of Revelation is like a department store in that if you go to it regularly you learn where everything is, and you get a feel for the layout so that you know what you will find in each different section, often with the help of a numbered store plan.
Bible-believers know that God communicates through visions and dreams, and discussions of these visions and dreams involve much examination of their symbolic imagery.
Will any of us ever actually get to see Jesus as the Lamb as John did in his vision? We see such metaphorical things in our minds, and accept them in our spirit as God intends, so if God wants us to see and be in the presence of Jesus as the Lamb of God He will make it so.
That's all for now. I would like to come back to the other points raised, but sufficient to say that we know from the opening of the Seven Seals that Conquest, Conflict, Commodities, Carnage, Complaint, Catastrophe, & Clarion are integral to the Perfect Completion of the Divine Plan.
