How do we know that God preserves His elect?

The undeniable truth of God's preservation of the elect is rooted in His sovereign will and the active role of the Holy Spirit in their lives. As mentioned in Jude, believers are 'sanctified by God the Father and preserved in Jesus Christ.' This preservation is not a result of human effort but is solely attributed to God's grace. Throughout Scripture, such as in 1 Peter and 2 Thessalonians, we see that it is God who not only chooses His people but also equips and keeps them through faith until the final day of salvation. The assurance found in God's immutability guarantees that those He has called will be preserved eternally.
