No, you are MISSING the whole picture: first take note that when John first saw into the throne room, JEsus was NOT at the right hand of the father - when we have at least a dozen verses telling us that He should have been there. God did this ON PURPOSE. The REASON He was not there is because He left heaven to be born of a virgin. We know that at this time, Jesus was STILL ON EARTH.
Next we take note that in the search for one worthy to break the seals, NO MAN WAS FOUND. If we read ahead we know that Jesus was found, but NOT IN THIS FIRST SEARCH. Now we know that it is BEFORE Jesus rose from the dead - for the moment He rose from the dead, He was found worthy.
Then we see as final proof that all this was before Jesus ascended, the Holy Spirit is still in the throne room (chapter 4). Then sudden a CHANGE. (We see the movement of time). We understand that as soon as the first search ended in failure ANOTHER search started. I am convinced this search for one worthy had been ongoing since Adam. But in the next search, SOMETHING NEW! Jesus was found worthy to break the seals! (Hallelujah!) Now we have the time pinpointed: It is now the VERY MOMENT (or a few seconds later) that Jesus rose from the dead. He was immediately found worthy to break the seals. And then John saw the moment Jesus ascended back to the throne room He left 32 years before. Now we have the time right after He told Mary not to hold onto Him. So we see this passage of scripture includes TIMING and the MOVEMENT of time.
God is God. If He chose to show John some moments of history, He certainly could and the proof is, He DID. God wanted to introduce John to the scroll with 7 seals. He chose to show John the very moment that scroll passed from the hand of the Father to the hand of the SON. To do that He had to show some history.
I see it as a simple statement of fact: John would be shown future events. And that certainly happened.
You can believe that or not, as you wish. It is man's human reasoning. In very plain English it tells us how Satan used King Herod to make an attempt on Jesus' life as a child. In fact, you can use an online planetarium and go back to 2 BC and look for those exact signs in the sky. I know because I did it. The crown of 12 stars for her crown was very unusual, for at that time, and ONLY that time, there were 9 stars and three planets in her crown. Jupiter only passes through the crown of Virgo every 12 years. HOWEVER: you may also be right. This same sign, from what I have read, will happen again in 2017. I have not verified it. Again there will be 3 planets in her crown. So these verses may well have a second meaning.
I can only tell you pretty much word for word what God spoke to me:
"Chapter 12 was Me introducing John to the Dragon, and in particular what the dragon would do in the last half of the week. Count how many times the Dragon is mentioned, including pronouns." (He waited for me to count.) "I also chose to show John how the Dragon tried to kill me as a child. You see that in the first five verses." (He waited for me to read them.) "Those first five verses were a 'history lesson' for John." (After a few seconds or minutes He then said I could go back and study chapters 4 & 5 again. You see, I was STUCK. He had asked me three questions on those two chapters, and I could not answer even one! I struggled with those questions for perhaps two weeks of intense study....hours every day. God chose this method (going to chapter 12) to show me how to find the answers.
It is refreshing to have a civil conversation! All I can say is, when God finished teaching me chapters 4 & 5, I was convinced of what He taught me. Just as those in the New Testament were sure of the things God revealed to them, I am sure.
