Step-by-step explanation:
Predestination is the doctrine that asserts that God has predetermined all things, including who will be eternally saved. According to this doctrine, a person is either saved or dam`ned from the time of their birth. It was popularized by John Calvin and had a significant influence on the theology of Calvinists and Puritans.
The idea of predestination suggests that God has already chosen those who will be saved and those who will be dam`ned, and that human actions cannot change this predetermined fate.
