Hey Eileen!
Yes the Lord will be appearing! but............
Verse 36:
Mat 24:36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
You don't know the day nor the hour he will appear.
After his appearance you will know that he has appeared.
Yes, thats the order of events
easy as 1,2,3
Verses 29,30,31
Can you know when? Yes, after it(his appearance) has already happened.
Don't forget, we don't know when(day, hour, minute, sec) that he will make his appearance.
We won't know until it has happened.
Here a an excerpt from Lake of Fire 13:
And so our Lord’s testimony of a beast out of the sea is a beast out of the sea, "which IS, and which WAS, and which IS TO COME." For just once in your life BELIEVE your Lord, and just maybe you will begin to learn and understand the truly "DEEP things of God."
But how can I say that this beast out of the sea is something that already existed at the time of John’s writing? Was he not to write about "…things which must shortly COME TO PASS…"? (Rev. 1:1). Is this not then making all that John sees, things that are all in the future from the time of his vision? No. Everything in this book is part of Christ’s testimony, "which IS, and which WAS, and which IS TO COME." It is needful that we read several verses now to catch the significance of, from what perspective it was that John wrote this prophecy:
"I John, who also am your brother, and companion in tribulation, and in the kingdom and patience of Jesus Christ, was in the isle that is called Patmos, for the word of God, and for the testimony of Jesus Christ [‘which IS, WAS, and WILL BE’].
I was IN THE SPIRIT on the Lord’s day, and heard BEHIND ME a great voice, as of a trumpet [a trumpet is a symbol for a POWERFUL MESSAGE],
Saying, I am Alpha and Omega, the first and the last: and, What you see, write in a book, and send it unto the seven churches which are [they ALREADY existed at the time that John writes about them] in Asia…
And I TURNED to see the voice that spoke with me. And BEING TURNED, I saw seven golden candlesticks." (Rev. 1:9-12).
Ah yes, John heard this trumpet (or message) "behind him" and therefore, had to TURN BACK in order to see, hear, and understand the message! And so John writes about the things he sees "BEHIND" him (1:10), and "…things which must be HEREAFTER."
I hope that helps
As for Satan:
Rev 20:1 And I saw an angel coming down out of heaven, having the key of the abyss and a great chain in his hand.
Rev 20:2 And he laid hold on the dragon, the old serpent, which is the Devil and Satan, and bound him for a thousand years,
Rev 20:3 and cast him into the abyss, and shut it, and sealed it over him, that he should deceive the nations no more, until the thousand years should be finished: after this he must be loosed for a little time.
Eileen I hope this helps.
