The "Perseverance of the Saints" is a theological concept primarily associated with Reformed theology. It asserts that those who are truly saved will continue in their faith until the end of their lives. This means that genuine believers cannot lose their salvation, as it is secured by God's grace. This doctrine emphasizes the importance of a lasting relationship with God and encourages believers to remain steadfast in their faith. It suggests that while Christians may face challenges and struggles, their ultimate salvation is assured, reflecting the belief in God's sovereignty over their spiritual journey.
