I think that part 3 far outdoes part 1, so I would recommend skipping over to that one. An added bonus of part 3 is that it does not rely that much on Malachi Martin. The interpretation of the Miracle of Sun in that video is essentially that it was a kind of vision of how the sun will appear during the Chastisement. The sun will appear to move about because of the global earthquakes along the fault lines, which will dramatically shake the surface, making it appear to people on the ground as if the sun is moving. One could interpret this according to an FE or GE geocentrist cosmology. (That is not where his analysis of the Miracle of the Sun ends, however, so I recommend listening to all of what he has to say about that).
He reinterprets the tip of the spear differently in part 3, as some kind of potential solar flare or perhaps a flaming sword of an Angel. He’s not definitive about it, but he moves away from the previous interpretation about it being some kind of Russian superweapon.
A connection: since there are angels who have been given power to govern nature, it makes sense that there are angels that govern the sun, and that an angel could draw up a solar flare, or as it would appear, a “tip of the spear”, to use as an instrument of Divine Justice if it was commanded to do so by Almighty God.
