Students should be open enough to, prayerfully consider more sacred teachings. There is a station in life where each person has to ask himself, am I going to apply what I learn and pray about it. A closed book will be sealed. Kept secret till end times. Sealed the book for end times.
Diligent students are to consider such a possibility.
When the sealed book of Daniel is revealed in the latter days a prophet will reveal it. It continues on to tell that Daniel did not know what it meant. A few well-known quotations from the New Testament would be enough to establish the reality of reticence as an essential principle of the gospel teaching. All men cannot receive this saying, save they to whom it is given. Scriptures evidence that something is being withheld.
