How do we know if we are one of God's sheep?

In John 10, Jesus explains that His sheep hear His voice and follow Him, affirming a unique relationship between the shepherd and the sheep. The assurance comes not merely from self-identifying as a sheep, but from the genuine response to His call. If one finds themselves yearning to follow Christ and recognizing their lostness without Him, it is a strong indicator of being among His flock. Moreover, the sheep express dependence on the Shepherd, acknowledging that outside of Him, they are lost and require His guidance.
