Is it necessary for people to believe in the dark spirit and extraterrestrial agendas for your prayer for saving humanity to be effective?

It will be helpful and of value for them to be informed as this will help their intention to be the most fully aligned possible with the application of love energy they are requesting, but it is not absolutely essential. So there will be many who cannot embrace the full import of your teachings with respect to the interlopers, but nonetheless will have a great desire to see a benefit from effective prayer requests and will be inclined to try your recommendation. And as we said before, the broad nature of the request will give us some latitude to apply the love at our discretion, including the influence on them of the interlopers, and that will allow addressing these concerns even for the skeptical, at least to some extent.
