Are you familiar with the Gregorian calendar or the liturgical calendar?
Both are counterfeits to our Heavenly Father’s calendar that uses His sun, moon and stars for signs, seasons, days and years... all calculated calendars use only pieces of His clock.
His calendar shows us, with His New moons, Sabbaths and Feasts, our Messiah’s life on earth and His coming Kingdom...
Israel was given it... and abandoned it.. although they will have some sort of template a couple times a year ( unless His feasts conflict with their pope appointed weekly sabbath)
The new moons, Sabbaths and feasts were perfectly fulfilled with our Messiah with His birth, circumcision, dedication, baptism, death, rest in tomb, and resurrection..
All of those big events for our Messiah fell on a new moon, Sabbath or feast found only on His calendar..
And scripture confirms it or shows hints to each of these if one seeks.
But the bride appears happy with december 25 and easter ‘instead of’ the genuine.
Those are counterfeits if one learns His timekeeping...but it won’t be taught by a church who accepts the world and its timekeeping premises and traditions that trump scripture.
I only know it by His grace and mercy. It isn’t new.. it is very old..
All praise and glory is His!
