There's a pretty easy out for someone determined to believe in this stuff: their own act of prayer itself was part of God's plan.

Also, these types of theists usually justify these outwardly incompatible beliefs with a distinction between "true" free will and the "perception" of free will. In some people's deterministic view, while God has this omniscient perspective that spans all of space and time, the human perspective is one of the impression of freedom, a sense that feels so real that you might as well call it it simply "free will".

Probably figured they could get married real quick and everything would be fine, "Trump's only going after the thieves and rapists".

That's exactly who he is trying to appeal to.
