I disagree. I think when the 70th week begins, most believers in the world will know. Why? Because it will be after the rapture and then after the great, worldwide earthquake of the 6th seal that kicks off the Day of the Lord. The next events will be the first trumpet judgments. They will be very hard to miss, as will this great earthquake.
the tribulation is something Jesus preached and taught that many of his disciples would have to endure because they were in the world yet
see how he is preparing them to go through this great tribulation ?
“And Jesus answering them began to say, Take heed lest any man deceive you: For many shall come in my name, saying, I am Christ; and shall deceive many. And when ye shall hear of wars and rumours of wars, be ye not troubled: for such things must needs be; but the end shall not be yet. For nation shall rise against nation, and kingdom against kingdom: and there shall be earthquakes in divers places, and there shall be famines and troubles: these are the beginnings of sorrows. But take heed to yourselves: for they shall deliver you up to councils; and in the synagogues ye shall be beaten: and ye shall be brought before rulers and kings for my sake, for a testimony against them. And the gospel must first be published among all nations. But when they shall lead you, and deliver you up, take no thought beforehand what ye shall speak, neither do ye premeditate: but whatsoever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Ghost. Now the brother shall betray the brother to death, and the father the son; and children shall rise up against their parents, and shall cause them to be put to death. And ye shall be hated of all men for my name's sake: but he that shall endure unto the end, the same shall be saved.
But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light, And the stars of heaven shall fall, and the powers that are in heaven shall be shaken. And then shall they see the Son of man coming in the clouds with great power and glory.”
Mark 13:5-13, 24-26
you see he’s telling them up front they will go through these things he’s preparing them to endure instructing then how to get through it
For in those days shall be affliction, such as was not from the beginning of the creation which God created unto this time, neither shall be. And except that the Lord had shortened those days, no flesh should be saved: but for the elect's sake, whom he hath chosen, he hath shortened the days. And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not: For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect. But take ye heed: behold, I have foretold you all things.”
Mark 13:14-17, 19-23 KJV
see how he is readying those who will hear him to endure the trial ahead ?
“But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light, And the stars of heaven shall fall, and the powers that are in heaven shall be shaken. And then shall they see the Son of man coming in the clouds with great power and glory. And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.”
Mark 13:24-27 KJV
my thing is to go back to Daniel and try to reject this for the sake of my own interpretation of Daniels seventy weeks , which were shortened anyhow , doesn’t change what God said when he came to speak these truths they were all prophecy of of beforehand it never came clear until Christ arrived the rest was witnessing it was coming Christ revealed it all
the seventy weeks had to do with the messiah being cut off .
