Daniel 12:4
“But you, Daniel, shut up the words, and seal the book until the time of the end; many shall run to and fro, and knowledge shall increase.”

Daniel was a brilliant, faithful, knowledgeable man of God but he lived 2,500 centuries ago and much has changed.
Now I believe those living in those days had inventions, machines, and methods that are lost and unknown to us. Simple ways of accomplishing the complex things we do today.
Still, mankind’s knowledge and technology have increased exponentially since Daniel’s prophecy.
Things his world could not understand are revealed to him creating more questions than answers.
He is told to shut up the words and seal the book until the end time.
You now live in the end time, at least it’s more of an end time than when Daniel lived.
Reading Revelation still spawns many questions but I feel you can understand more of it than people could a 2,500 or one hundred years ago.
The closer the day comes the more clearly you will see it.
The book would actually be a scroll and in the Book of Revelation, the Lamb is given a sealed scroll to open.
Only Jesus can reveal and unfold the events of the time of the end.
I encourage you to put your trust and your life in His hands.
