Who believed that God predetermines who will be saved?

The belief that God predetermines who will be saved is known as predestination, and it has been a topic discussed by various religious and theological groups throughout history. One well-known advocate of predestination is the Protestant theologian John Calvin, who developed the doctrine of "double predestination." According to Calvin's teaching, God not only predestines some individuals for salvation but also predestines others for damnation. This concept is a key component of Calvinism, a branch of Protestantism. However, it is important to note that not all Christians or religious groups agree with or accept the doctrine of predestination.
