Amen.
As the WCF reminds us, "there shall be always a Church on earth to worship God according to His will."
But at the same time, there are pretenders and false Christs and false prophets who seek, if it were possible, to deceive even the elect.
We know them by their evil fruit and by their lack of adherence to the Bible as their rule of faith and practice.
What if God permitted an exercise in self-determination for a purpose, and then stepped in with a pre-plan He had to repair it when the damage was evident?
But that implies God permitted this exercise to see what happens. And we are agreed God knows everything long before it happens. There's never a point in time when God waits for an outcome He has not set in motion to accomplish His ultimate goal.
I think it's more consistent Biblically to say whatever "is" at this moment in time is exactly how God has determined this moment to be, for His own perfect reasons. One day we'll know why. It's just as Paul says, "For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known."
I wasn’t implying that God doesn’t know what will happen. A pre-plan and plan by God for a purpose doesn’t mean that God doesn’t know. (or you can think of it as plan with parts A & B) It just mean the plan must run its course, if He so desires it, for His purposes.
I agree that this is consistent with how the Christians see God, and there is biblical suport for that, but there are instances in the Old Testament where God has to "come down and see..." so he "will know" (LOL) [Gen 18:21] and numeorus other examples.
