I don't think this is the correct interpretation of Q. It doesn't make sense that an FBI individual/group would go to so much effort to lead us. Lead us where?

I think Q was who he said he was. He was probably somewhat close to Trump. He probably had access to a lot of (mostly publicly available) information. But my guess is he believed God was on his side, or the movement's side. When he said, "nothing can stop what is coming" it's not because he was sitting on a mountain of evidence that would be released in time. Rather he believed there was a mountain of evidence and God would reveal it in time.

Many Christian leaders prophesied that Trump would win re-election. Paula White is Trump's personal spiritual adviser. American Christian society reached a critical mass of spiritual leaders that believed Trump would bring about a new era of freedom. When that happens these spiritual leaders become emboldened because they see other spiritual leaders, people they trust, prophesying the same thing, therefore it must be God's will.
