. . .Tying this better to the topic, lets consider why Jesus doesnt add a parable where he tells his diciples that knowledge of the prophecies are an important factor in being prepeared? . . .
Tomas, Christ didn't use a parable to highlight the importance of a prophetic understanding because He wanted to underscore the issue by telling us directly to study and understand the prophecies of Daniel. This is the only direct instruction of Christ to study a certain area of scripture - the abomination of desolation spoken of by Daniel. It was of such importance that He told us directly in plain language to study it.
And, in addition to that direction, so that no one would be left wondering what weight should be attached to them, He also gives us three admonitions in Revelation to study and understand those prophecies.
