Open theism
Open theism, also known as openness theology and free will theism, is a theological movement that has developed within evangelical and post-evangelical Protestant Christianity as a response to certain ideas related to the synthesis of Greek philosophy and Christian theology. It is typically advanced as a biblically motivated and philosophically consistent theology of human and divine freedom (in the libertarian sense), with an emphasis on what this means for the content of God's foreknowledge and exercise of God's power. It has been said that open theism triggered the "most significant controversy about the doctrine of God in evangelical thought" in the late 20th and early 21st centuries.
Exposition of open theism
In short, open theism says that since God and humans are free, God's knowledge is dynamic and God's providence flexible.

Thus, the future as well as God's knowledge of it is open (hence "open" theism). Other versions of classical theism hold that God fully determines the future, entailing that there is no free choice (the future is closed). Yet other versions of classical theism hold that even though there is freedom of choice, God's omniscience necessitates God foreknowing what free choices are made (God's foreknowledge is closed). Open theists hold that these versions of classical theism are out of sync with:
