What does the Bible say about losing salvation?

The possibility of losing salvation has been a contentious issue among Christians; however, Reformed theology maintains that genuine believers, once saved, are eternally secure in Christ. The New Covenant assures that God's people will have His laws written on their hearts (Hebrews 8:10), which indicates a transformative work of the Holy Spirit that preserves faith until the end. Verses such as Romans 8:38-39 emphasize that nothing can separate the elect from the love of God, reinforcing the belief that salvation is not conditional or revocable.
