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 = God’s Sovereignty …

While Arminianism = Human autonomy.

Rather, Biblical doctrine shows that God is so sovereign …

He can offer not only undeserved grace, but also the undeserved choice to accept or reject that grace.

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