How does the concept of eternal security relate to being one of Christ's sheep?

The concept of eternal security is deeply rooted in Jesus' declaration in John 10:28 that His sheep shall never perish. This assurance comes with the understanding that salvation is entirely the work of Christ, and He promises that none whom the Father has given Him will be lost. This security arises from Christ's omnipotence; no one can pluck them from His hand. Therefore, true believers, as Christ's sheep, can rest assured in their salvation, knowing it is not contingent on their abilities or efforts, but solely based on Christ's finished work on the cross. Understanding this provides immense comfort and strength in the Christian faith.
