What does it mean to never perish according to John 10?

In John 10:28, Jesus promises that His sheep will never perish, which signifies the eternal security of believers. This assurance emphasizes that once a person is given eternal life, nothing can separate them from God's love or remove them from His hand. This doctrine is pivotal in sovereign grace theology, affirming that salvation is not dependent on human effort or merit but solely on Christ’s work. The verse reinforces the doctrine of perseverance, assuring the saints that their salvation is eternally secure, regardless of their shortcomings or failures.
