In biblical thought, some actions prefigure or anticipate or illustrate other actions.
I don’t believe the good Lord has let there be arrangements so “perfect” that they are airtight to the thought systems of sinful man. That could result in the bible getting idolized. “Bible codes” are an extreme example of this — while intriguing, they are at best witnesses to the omniscient origin of what the bible says on its face. From man’s point of view, God always seems to have a wild hair. Of course to God it isn’t wild — He knows exactly what it’s for and what it’s doing, and it fits into His perfect glory.
But I sure agree the way Isaiah divides into sections, and the way it spells out what was scheduled to take place at Calvary, is notable. Modern non-Christian Judaism overlooks all this, though it takes some effort with Isaiah 53. To me, that was the chapter that cemented the authenticity of Jesus’ sacrifice on the cross and allowed me to believe. People weren’t just speculating about it. It’s documented to happen, right there in black and white.
I tend to agree with you. As much as we study and think we have figured out what God is telling us from the Scriptures, about the time we think we are right, He tosses a curve ball at us.
We can study and study, but in the end more times than not we can do is actually play Johnny come lately in realizing He was telling us about something that happened, not is going to happen.
All the great theologians of the time tried their best to know when Christ was arriving the first time, and yet all those who were alive when it happened missed the boat. Obviously their hearts were not prepared for what He was actually going to come as. A servant, not a King. At least of this world and the first time.
Which tells me what is going to happen when He returns. I see many missing the boat who are sure they know the signs of the times.
The best we can hope for is to have our hearts ready for Him, and not worry so much about when the day is going to be.
Although it is all good for study and preparing our minds and hearts to be approved.
