6-25-18, Daniel and John's prophecies were written over 500 years apart, yet the two books unite with mathematical precision - both pinning the year 688 AD - that was hundreds of years in John's future and over a thousand years in Daniel's future!
When Khalifah Omar entered Jerusalem in 639 AD, he was met by Sophronius, Bishop of the Jerusalem Church, who showed him around the city. Seeing the temple mount (then in rubble), Omar declared that he was going to build a memorial to Muhammad on the original site of the temple of God. Sophronius exclaimed in horror, "Verily, this is the Abomination of Desolation as spoken of by Daniel the prophet, and it now stands in the holy place". Though Sophronius was a very old man of about 80, Khalifah Omar put him in prison and to forced labor, the severities of which killed him." -- Jerry Landay, "The Dome of the Rock" 
Is there an explanation as to why we couldn't see the perfect mathematical relationships between these two prophets before this "time"? Yes.* God said:
The Battle of Tours, France took place in 732 AD. This battle was fought exactly 100 years after Mohammed's death. The Battle of Tours is widely considered to be the most important battle of the entire Christian era. Charles "Martel" (the hammer), against astronomical odds, defeated the Islamic army, and the spread of Islam, in its near conquest of the whole known world, as it headed up through Europe during the Islamic First Jihad. Indeed blessed was he who patiently waited and made it through the First Jihad, without converting to Islam, or denying his Lord and Savior. History Jewish Library
This epic battle was the turning point marking the zenith of the Islamic onslaught delivering the mortal wound (Revelation 13:3) to the spearhead of the invading forces, and killing the literal head of the advancing army Emir Abd er Rahman. "Without his leadership and guidance, the other commanders were unable to even agree on a commander to lead them back into battle the following morning. The effect of the death of Abdul Rahman on both Islamic and world history was profound." According to one unidentified Arab, 'That army went through all places like a desolating storm.' sacking and capturing the city of Bordeaux, and then defeating the army of Duke Odo of Aquitaine at the Battle of the River Garonne — where the western chroniclers state, 'God alone knows the number of the slain'— and Odo fled to Charles Martel, seeking help."
Note: In 2018 we see the Islamic hordes once again on the march... 1286 years later. [to be cont'd]

*Isaac Newton, Matthew Henry and many of those before us understood that the book of Daniel, and by extension Revelation, would not be fully understood until the "time of the end".

1-24-20, Another historical act by this PRESIDENT DONALD JOHN TRUMP - personally speaks at the Washington DC annual 'March for Life.' There was a time in Pres Trump's past when he was uninformed and supported 'a woman's right to choose' killing her child. But then he became educated on this issue and now supports the 'CHILD'S right to LIVE!'
