Jesus is the good shepherd: we are the sheep of His flock, we can hear His voice. We can discern His voice from all others. The Bible says: "The sheep follow Him for they know his voice. Yet they will by no means follow a stranger, but will flee from him, for they do not know the voice of strangers." How do we know the voice of the Lord who is our great shepherd? We know by spending time with Him, we know by reading His Word and knowing His will through the Word.
