Do spirit guides know the future?

Do all Spirits know the future?

No—but in some cases, under certain conditions, they can tell what is about to happen, but this knowledge is not their own. 

If they are interested in the welfare of a person, one under their care, they may receive knowledge of the future in regard to their charge from a higher source.

The guardian spirit may be unable to prevent that which is foreseen—say, a shipwreck—but he may impress the mind of his charge in such a way as to cause him, when bent on going with the ship, to miss his passage. The vessel sails without him. He hears of the disaster, which befalls her, and he cries out, O, how lucky it was I was unable to get with her! 

There was no luck in it. It was pure prevention by his guardian spirit.
