This is the crux of the issue. How do we find that area that exists between deism on the one hand and determinism on the other?
I think the article makes it clear that the area you speak of is not ours to find. "They desire to tread where theological license has not officiated them to travel. I suppose, then, we could say with the proverb, "Curiosity killed the cat." For Hyper-Calvinism, unwarranted curiosity in the decrees and counsel of God has caused them to enter a realm where God has not revealed Himself."
I think a big problem I have seen on these threads is that there are those who think they know that area like the back of their hands. (Both Calvinists and Arminians). They have it all mapped out. They know all the roads. Or so they think.
