Irenaeus, in Against Heresies, 4.37.2-3, averred in the face of Gnostic determinism that the prophetic rebukes for spiritual evil and exhortation of spiritual good presupposed human ability to obey, as did the religious teachings of Jesus. Hence both Old and New Testaments substantiated the self-determination of humanity. By libertarian freedom I mean that our freedom is a derived freedom, humans are not completely independent or completely autonomous. In Molinism, unlike Calvinism, God is completely sovereign over the eternal destinies of a world of libertarian free creatures who have, in Augustinian terminology, “free choice” and not merely “free will.” For Augustine, “free choice” (i.e. libertarian free will) entailed the freedom to choose between opposites in both the physical and spiritual realms. Thus fallen humanity, by virtue of the imago Dei, can freely choose whether or not to respond to God’s prevenient grace. By contrast, Augustine defined “free will” (i.e. compatibilist free will) as the ability to choose without any external constraint between the options compatible with one’s nature. On this view, unregenerate humans, due to original sin, lack the ability to choose between spiritual good and evil. Just as a bad tree can bear bad fruit or no fruit at all, unregenerate humanity can either perform spiritual wickedness by actively rebelling against God or do nothing spiritual at all by displaying passivity toward God.  The Scriptures breathe libertarian human freedom, even if the Bible makes no explicit mention of it. Take, for example, 1 Cor. 10.13, which promises that God “will not allow you to be tempted beyond what you are able, but with the temptation will provide the way of escape also, that you may be able to endure it.” It follows that any Christian who does not in some circumstance endure but succumbs to temptation had it within his power to take the way of escape instead, i.e., he had the liberty of opposites in those circumstances. Again, we can at least agree that if the Scriptures do presuppose or affirm libertarian freedom, then there is no basis for denying that sentences like 1 Cor. 2.8 are true counterfactuals of freedom.
