There’s a lot of different kinds of old objects – from coins to plaques to bells to Bibles to even window leads – which have dates starting with a “J” rather than a “1”.
It’s possible, but not certain, that these are from the 1000 year millennial reign of Jesus Christ. See the gallery below.
The window lead images are the hidden markings left by the maker on old windows, which cannot normally be seen unless you pull it apart. I think it’s a pretty compelling example.
I haven’t included in this gallery the many examples of dates with an “i” at the front instead of a “1”, which some say means Iesous (the Greek way of saying Jesus). There’s plenty of these.
This is a harder case to make because there’s books for example that i’ve seen which have a capitalised “i” instead of “1” at the start of the publication date, but then they also use the “i” as a 1 in other areas too.
The “J” dates are far more compelling. Some say it’s a reference to the Julian calendar, but I don’t think that fits here in the context.
If these J dates are evidence of the millennial reign it would align with the other evidence we see indicating the second coming of Christ is in the past, such as the advanced old world architecture and the “meltology” (melted buildings) evidence.
And of course it would align with the scriptures, where throughout the gospels and Revelation we are told by Jesus that he’s returning quickly to the same generation. And the apostles all spoke like he was returning within their lifetimes, not 2000 years later.
As ever, the real world evidence continues to back up the scriptures as being 100% truth.
