Does the Bible teach that believers can lose their salvation?

The doctrine of perseverance of the saints affirms that those who are truly saved and chosen by God will not ultimately fall away from their faith. Romans 8:30 speaks to this certainty, indicating that those whom God called, He also justified and glorified. Similarly, John 10:28-29 assures us that Christ's sheep will never perish, and that no one can snatch them out of His hand. This reflects God's faithfulness and guarantees that true believers, who have been given faith and called by His grace, will be kept until the end.
