Dear brother in Christ,
. Revelation directly reaffirms what Daniel said, which was sealed to him and not revealed in Revelation. The same numbers referring to the time of the end appear in both, which meaning was indeed "sealed’. Refer especially to Daniel, to whom Jesus specifically referred:
Mattew 24:15 “Therefore when you see the abomination of desolation which was spoken of through Daniel the prophet, standing in the holy place (let the reader understand)” Jesus speaking to “When shall these things be and what shall be the time of thy coming?”
. Well, my friend, no one is obligated to belief anything, whether Daniel had visions of when the crucifixion of Christ would occur after 70 weeks = 490 years following the decree of Artaxerxes in 457 BC, which accurately predicted “Messiah shall be cut off” in 34 AD, or thereabouts. Or his vision of 2300 days (years) from that starting point the time of the end would be fulfilled, which was 2300 - 457 = 1843 + 1 (no year zero) = 1844. Or that time (360) + times (720) plus 1/2 time (180) = 1260 AH = 1844
Nor are we obligated that John had visions of 3 1/2 days (years) x 360 = 1260 years, or that 42 months x 30 = 1260 AH, thus proving Muhammad in prophecy, since 1260 AH is 1844 AD
Nor are we obligated to believe that Jeremiah was right when he said the “Lord shall set His throne in Elam”, which is where Daniel had his above vision. Elam is SW Persia, where in 1844 AD (1260 AH) The Lord did just that when the Bab appeared, announcing the coming of Baha’u’llah in 1863 AD, which is 1280 AH (again see Daniel).
We aren’t obligated to believe anything, but I testify to the truth of all of the above, including Daniel, Jeremiah, John (I know too much to keep silent)
God bless you abundantly, my dear brother
