Okay, here’s how I see it, refute as you will.
God is watching over us, this world of ours sitting before him, with time running by as a giant tapestry. He has many different colored threads representing the people of various calibers who could fulfill each completely necessary role within the sphere of history. He also knows to what level he can rely upon these people to use their agency in the way he needs them to, for them to be at specific fixed points in time that HAVE to happen to make the plan work. At time he puts challenges in their way or takes someone out of their life to influence them toward specific points, but he cannot MAKE them choose anything. He’s gently coaxing along events that need to happen, without being able to directly change them through the people themselves, because of their agency.
So he sets up situations, trials, etc. and uses their own personality and normal reactions to guide them toward that point. They can still CHOOSE to walk away from it completely, but the majority of the time they make the right set of choices to fulfill the biggest blessings set out in their P.B.
However those who don’t follow the prescriptions: scripture study, prayer, faithfulness… will not receive the blessings laid out, because they didn’t strive for them.
My own patriarchal blessing is so full of things I can barely even accept the scope of that it’s daunting, to say the least. But it’s exciting too, as I continue living as a disciple of Christ, to see where I could end up…
