Perseverance of the saints

Perseverance of the saints, sometimes called preservation of the saints, is a Calvinist doctrine that asserts that the elect will persevere in faith and ultimately attain salvation. This concept was first developed by Augustine of Hippo in the early 5th century, based on the idea of predestination by predeterminism. In the 16th century, John Calvin and other reformers incorporated this idea into their theological framework. The doctrine of the perseverance of the saints is rooted in this specific understanding of predestination and remains a central tenet of Reformed theology today.
