Molinism is an attempt to provide a solution to the classic philosophical problems associated with God's providence, foreknowledge and the freedom of humanity. This view may be traced to the 16th century Jesuit theologian Luis de Molina - hence, the name Molinism. Specifically, it seeks to maintain a strong view of God's sovereignty over creation while at the same time preserving the belief that human beings have self-determined freedom, or libertarian free will.
Notice that Molinism starts with the belief in libertarian free will. Then it tries to fit it in with Scripture.
Provisionism is a modern theological system within Southern Baptist circles, particularly promoted by Leighton Flowers, which seeks to offer an alternative to both Calvinism and Arminianism. While not identical to Semi-Pelagianism, Provisionism shares striking theological similarities, especially in its denial of the necessity for a prior work of the Holy Spirit to effect any inner grace—whether regenerative or prevenient—to enable faith. Provisionism teaches, rather, that the Holy Spirit operates solely through an external influence, illuminating the truth of the gospel (externally), convicting of sin (externally), and drawing all people who hear (externally), making the gospel clearly understood without altering the individual’s inner nature or will, thereby leaving the response entirely to unregenerate human volition.
