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 belief emphasizes that genuine believers cannot lose their salvation, as it is secured by God's grace. This doctrine is often linked to the idea of eternal security, suggesting that once a person has accepted Jesus Christ as their Savior, they are assured of their place in heaven. It encourages believers to remain steadfast in their faith, trusting that their salvation is ultimately upheld by God's power.
