Is it possible for a believer to lose their salvation?

The doctrine of eternal security asserts that once truly saved, a believer cannot lose their salvation. This is affirmed in John 10:28-29 where Jesus proclaims that He gives eternal life to His sheep, stating that no one can snatch them out of His hand. Furthermore, in Romans 8:38-39, Paul emphatically declares that nothing can separate the elect from the love of God in Christ. This conviction is rooted in the sovereignty of God, who ensures the perseverance of the saints. Therefore, true believers, chosen by God, will ultimately endure to the end.
