Disclaimer: I have no idea about anything definite regarding the end times, Armageddon, the Gog Magog War, the new millenium, except for the vague mental pictures we get from scripture.
These things are so mind-boggling to me, and I know that speculations abound, and have succumbed to some speculating myself, however, the truth is what it is and sometimes we just won't know until the day we see it happening. In the meantime Jesus only cautioned us to understand the times from the point of being aware of today, this moment in time. He does not require that we understand everything about what will happen tomorrow, next week, or next year, but to remain faithful and aware today, to keep our eyes open and lifted up in anticipation that it can be any time....and in fact if I were to die today, my next moment of what I will experience will be what is often called "the rapture" or the resurrection of the saints (some might also speculate that we will have awareness between that time of our death and the time our body is reunited with our spirit to again be a living soul...I guess we will know for sure when that happens.
I was watching a few Youtube videos about the Gog Magog War, and a few different ideas circulating about what it is and when it will happen....and it made me realize that with all of scripture the Lord wisely gives us just enough "manna" for today. He knows that our puny brains would implode with all that He knows, so He gives us just enough for today. As Jesus put it:
Matthew 6:33-34 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself.
Sufficient unto the day is the evil thereof. (KJV)
So when I read the scriptures, I store away treasures that as the Lord sees the need, will bring to my remembrance and understanding the need of them for each day as it comes. I can learn from Mary:
Luke 2:19 But Mary kept all these things, and pondered them in her heart. (KJV)
There is so much that we do not know, but so much that has already been revealed to give us enough food for thought to get us through the evil that will face us today, and Jesus promised that tomorrow would take care of itself, and we would be wise to continue to seek His righteousness (prayer).
