The belief that human souls choose good or evil totally independently of God's will, which is most often found among the more extreme Arminian Christians, means that God does not ultimately determine the will of each soul. However, "ex nihilo" creation, a belief also commonly found among Arminians, means that God determined everything that exists, including the will of each soul, without drawing on anything but himself. The question is definitively resolved in Calvinism by asserting that all souls act according to God's sovereign will, and in Mormonism (see below) by asserting that human souls have always existed and are co-eternal with God.
