What does the Bible say about being a sheep or a goat?

In Scripture, particularly in John 10, Jesus identifies Himself as the good shepherd and His followers as His sheep. He makes a clear distinction between sheep and goats, illustrating that sheep hear His voice and follow Him, while goats are unable to follow because they are not His (John 10:26). This metaphor highlights the sovereign grace of God in electing some to salvation while leaving others in their spiritual blindness, affirming the critical idea that one’s nature is revealed through their response to the gospel. As Jesus Himself stated, 'My sheep hear my voice, and I know them, and they follow me' (John 10:27).
