I agree, however they warn us about our potentially devious minds
Yeah, also they tell us that speculation is futile when it comes to some things, simply because our minds will never come up with the answers, like how Creator Sons incarnate.
20:6.1 Let the sublime knowledge of the mortal life of Jesus of Nazareth sink into your souls, but waste no thought in useless speculation as to how this mysterious incarnation of Michael of Nebadon was effected.
Speculation about the future is sometimes pointless too.
55:10.9 Speculation concerning the function of these Creator Sons in connection with the outer universes now in process of preliminary assembly is wholly futile.
Mystical speculation can be dangerous if taken too seriously.
100:5.6 The great danger in all these psychic speculations is that visions and other so-called mystic experiences, along with extraordinary dreams, may be regarded as divine communications to the human mind.
Religious speculation can be detrimental.
102:3.2 Religious speculation is inevitable but always detrimental; speculation invariably falsifies its object. Speculation tends to translate religion into something material or humanistic, and thus, while directly interfering with the clarity of logical thought, it indirectly causes religion to appear as a function of the temporal world, the very world with which it should everlastingly stand in contrast. Therefore will religion always be characterized by paradoxes, the paradoxes resulting from the absence of the experiential connection between the material and the spiritual levels of the universe – morontia mota, the superphilosophic sensitivity for truth discernment and unity perception.
Jesus warned his apostles against taking speculation seriously when it came to understanding his teachings. This is where they actually went wrong after Pentecost.
151:2.8 In your own hearts you may often profitably engage in such flights of the speculative imagination, but you make a mistake when you seek to offer such conclusions as a part of your public teaching.
Speculation, theorizing, hypothesizing, pondering . . . they’re all good activities for the mind. But our minds are not divine. Not every thought we have is a useful thought. We must develop sufficient wisdom in order to determine which thoughts are serviceable and which ones should be discarded. There’s individual wisdom and group wisdom. Let wisdom prevail!
102:3.2 Religion must continually labor under a paradoxical necessity: the necessity of making effective use of thought while at the same time discounting the spiritual serviceableness of all thinking.
9:5.6 Mind, on Urantia, is a compromise between the essence of thought perfection and the evolving mentality of your immature human nature. The plan for your intellectual evolution is, indeed, one of sublime perfection, but you are far short of that divine goal as you function in the tabernacles of the flesh. Mind is truly of divine origin, and it does have a divine destiny, but your mortal minds are not yet of divine dignity.
