There is a book with this title (The Gospel in the Stars). It is a very interesting and well done book
Some of these speculations/prognostications are quite interestingly curious indeed.
I believe in applying screens of Scripture early in such cases, to avoid expending effort (and squandering honor) barking up the wrong trees. Here are a couple of examples:
(1) Are there other events that are predicted to come sooner, and are they even likely?
(2) Is something derivable from this theory that would violate a Scriptural assertion (e.g. no one knows the day or the hour at which Christ will return)?
Another observation I would wish to make is that (3) biblical events often have pre-echoes. They are anticipated by other events. This often appears to be the Lord’s way of keeping people thinking about important principles, as history plays out in its slow way. Don’t mistake the pre-echo for the prophetically featured event.
But I have my own pet prognostication which, I think, does pass the Scripture test. God can work things out in a number of ways we could never anticipate, though, so I never elevate this to dogma.
Perhaps Christ is going to return within a not completely died out generation after the re-founding of modern Israel, as diminutive as it currently is. This might put His return in the year 2028 or thereabouts (for an eighty year generation). Still no day or hour, so we aren’t speculating on something impossible. This also would be about 2000 years, more or less, after His crucifixion (especially if our Gregorian calendar idea of 1 AD is a bit late). Another scripture asserts that a thousand years is as a day. What if this, on the 1 day to 1000 year scale, were to parallel the two days Jesus was buried and on the third day rose again? (He’d rule and reign another 1000 years, completing out the third “day.”)
I honestly can’t say I know. It just hit me as a possibility, and with at least as much credibility as this book has.
