Questions about free will, its use, or existence
Free will (also referred to by more specific terms such as moral agency or libertarian free will) describes the ability to make choices, and in theological discussion frequently revolves around human accountability and responsibility for choosing between right and wrong.
Whether humans can control their own actions, or are entirely predestined, pre-programmed, or cause-effect autonomous is a subject of discussion in modern (and some not-so-modern) philosophy & theology.
Biblical texts are often considered relevant to the free will discussion because numerous texts give commands and speak of blessings or punishments based on how people respond to those commands.
