What does the Bible say about God preserving His people?

Preservation of the saints is a key aspect of God's promise to His elect, often drawn from passages such as John 10:28-29, where Christ states that His sheep will never perish. This preservation is not based on human effort but on the power of God, as emphasized in 1 Peter 1:5, which assures believers that they are kept by the power of God unto salvation. This doctrine provides great comfort, affirming the eternal security of every believer who has been sealed in Christ, illustrating that He alone is responsible for their ultimate salvation.
