Hi Barryjones,
This is an interesting scenario you have dreamed up here, as I think it raises some questions for how Christians and non-Christians understand God’s Will.
From your conversation “parable”, it seems like you are asserting:
P1) If Christians claim to know God’s will for someone, then they need to show what God’s will is for that person at any and every particular moment.
P2) Christians cannot show what God’s will is for that person at any and every particular moment.
C1) Christians cannot claim to know God’s will for someone (MT P1,P2)
P3) If Christians (and thus the Skeptic) cannot know God’s will for someone, then it is God’s fault for refusing to reveal his will to them (or the Skeptic)
C2) It is God’s fault for refusing to reveal God’s will (MP C1, P3)
It seems pretty clear that this expectation of knowing God’s will is a bit outlandish and would make any kind of claim about God’s will, or even our own wills, impossible to uphold.
Think of two students in a classroom who have just been assigned a project by their teacher. Student One turns to Student Two and says, “The teacher said we need to build this whatchamacallit.” If Student Two was to respond by saying, “well, you may think that the Teacher wills that, but you tell me, what does the teacher want me to do next in this very moment?” we would not assume that Student One knows nothing about the Teacher’s will for Student Two. Nor would we go even further to assume that the Teacher has refused to reveal their will to either student because they do not tell them what he/she wants in that very moment. What if all the Teacher wants is for the two students to work on the project, and the rest is up to them? Surely Student One can still claim to know the Teacher’s will, and Student Two can’t claim that the Teacher doesn’t want their will to be known by the students.
So, I think I’d reject Premise 1 and Premise 3, believing that they are a bit farfetched to assume as necessary for knowledge of God’s will. We don’t require this kind of knowledge in our other decision-making processes, so we don’t really need it here either, I don’t think Christians would even assert that God has an explicit will for every infinitesimally small moment of your life. It seems more like God has created beings like Godself, that have some kind of autonomy and free will to make the decisions they want to in response to God’s will.
