What does the Bible say about the security of Christ's sheep?

The Bible teaches that the security of Christ's sheep is guaranteed by the Great Shepherd Himself. In John 10:28, Jesus promises, 'I give them eternal life, and they shall never perish; neither shall anyone pluck them out of my hand.' This assurance highlights that true believers, referred to as His sheep, are held securely by Christ's power and love. Their salvation is not contingent upon their actions but entirely upon the faithfulness of their Shepherd, who does not allow any of His own to be lost. This security stems from the everlasting covenant of grace established before the foundation of the world, affirming that Christ's sacrifice was deliberate and sovereign.
