How do we know Jesus knows his sheep?

In John 10:27, Jesus states, 'My sheep hear my voice, and I know them, and they follow me.' This illustrates not only the intimate knowledge Jesus has of each believer but also the response of the believer to his voice. The ability to recognize and respond to Jesus' call is an indication of being one of his sheep. This dynamic underscores the doctrine of effectual calling, where the Holy Spirit enables the chosen to hear and respond to Jesus, leading them into salvation and guiding their lives. The connection is relational; the knowledge is one of love, care, and communion.
