Reformed Theology says it’s impossible to reject God’s grace when offered …

Based on the philosophic concept that doing so would involve human autonomy against God’s sovereignty.

The flaw is that Reformed Theology does not see that there is a third option, which runs throughout Scripture.

The choice isn’t Calvinism = a Sovereign God …

While Arminianism = Human autonomy.

Rather, Biblical doctrine shows a God who is so sovereign …

He can offer grace to those who have no choice in and of themselves, while also granting them the choice to reject that grace.

Denying God’s sovereign right to delegate that choice is, at it’s core, a denial of His sovereignty.
