What is the puritan doctrine of predestination?

The Puritan doctrine of predestination is the belief that God has already determined who will be saved and who will be damned, regardless of their actions or beliefs. This belief is based on the idea of God's sovereignty and the concept of the elect, who are chosen by God for salvation. Puritans saw themselves as part of this elect group and believed that living a godly life was a sign of being chosen by God.
